Hey I m a computer student and I need a project related to my field but it should include ARDUINO board in it which means it should be 60% hardware and the rest software. Can you please suggest me some of my requirement ? If it is possible please notify me

In the 1950s Popular Electronics published an article for constructing what was then a rudimentary computer game. It consisted of 21 lights with a ‘player’ button and a ‘machine’ button. A player,,could light 1, 2, or 3 lamps, the “machine:” could then also light 1, 2, or 3, lamps, each taking turns. The object of the game was to avoid being forced into lighting the last, or 21st lamp The “machine” would invariably win.. It worked on the principle that within the number 21, there are 5 groups of 4, with 1 left over. The secret was that whichever the “player” chooses (1,,2, or 3), the machine will always chose a number that adds up to 4. ( If the “player” chooses 1,, -the “machine” chooses 3,. If the “player chooses 2,,,the “machine” will choose 2.. If the “player” chooses 3, the , “machine will choose 1) The combination always adds up to 4. The original game used a mechanical ‘stepping’ relay and ordinary pilot lamps. I am looking for someone to take this on as a project using LEDs and processors. (Arduino maybe?) Will be glad to answer any questions.

Using Arduino in Project Based Learning Projects

Introduction: Using Arduino in Project Based Learning Projects

I'm a retired scientist who has spent his career successfully applying project based problem solving in real world projects. I am also a lifelong Maker/tinkerer with significant Arduino and software engineering experience. Last school year, in 2023, I had the opportunity to substitute teach five high school robotics classes (grades 8, 10/11) for several months. That was an amazing experience! It greatly increased my respect for STEM teachers, but also provided me with the unique vantage point to view an Arduino-focused high-school classroom from the perspective of my engineering design background. That led me to do an extensive review of published background on Project Based Learning (PjBL) that included Arduino technology. My overall impression is that teachers face some difficult challenges in order to take full advantage of Arduno's capabilities in STEM-PjBL teaching. Yes, I am a technologist, inexperienced in teaching, but many teachers are as inexperienced with Arduino, as I am with teaching. So I hope you will give me the opportunity to make some observations and suggestions aimed at helping you take better advantage of the possibilities to integrate Arduino in PjBL.

None of this requires rocket science, just information not included in the traditional basic Arduino training. As a result, I decided to make this Instructable with some suggestions for how teachers might push past stunted PjBL projects into full-blown PjBL successes for students. Here are some of the issues covered:

• Difficulty transitioning from the traditional didactic Arduino training sequence to a full PjBL training
• Spending to much time building modules that are never used vs jumping into gap-driven problem solving
• Confusion about when and where to apply the scientific method vs the engineering design process
• A structured end-to-end template for generic STEM-PjBL-Arduino instruction
• Pointers to quality references to accelerate student research discovery about Arduino resources
• Filling gaps in fundamental electric circuits knowledge and breadboard constructions
• Solving problems combining independent Arduino modules into more complex system creations
• A complete example of a STEM-PjBL-Arduino project to construct an Arduino RubeGoldberg device

The completed example was originally constructed as a demonstration of how Arduino can be used with multiple sensors and actuators to construct novel devices that would capture the interest of students. More details are available in a second Instructable: Arduino Rube Goldberg "Do Nothing Machine"

• Traditional Arduino Beginner Class experience
• Basic understanding and possible experience implementing traditional Project Based Learning in STEM
• Desire to take better advantage of the Arduino microcomputer in STEM oriented curriculum using PjBL methods

Step 1: Project Based Learning (PjBL)

Project Based Learning (PjBL) is a learning framework that has been called the future of education (1). PjBL is in contrast to more traditional Didactic Learning framework. In the didactic teaching model, the driving question or test is presented at the end of a unit. A simple diagram can help illustrate this (2). Traditional teaching with tests at the end looks like this:

– – – – – – – – – – – – – – – – – *T*

Each hyphen is a separate lesson, the culminating in a project or test at the end.

In contrast, a PjBL unit opens with the driving question, so the student starts with the end in mind. As a result, rather than the teacher driving learning "because you should know”, the student drives learning based on “need-to-know” to fill knowledge gaps found in the context of solving the driving question. The driving question is followed by a short sequence of focus activity lessons, represented by the hyphens below. These initial lessons connect the student to a driving question and provide necessary initial knowledge resources and skills. For example, if the DQ is art related, focus activities might include describing brush types and color mixing. Students then start the project phase and continue, focused on solving the problem until it is complete, like this:

DQ– – – – ________________________

In PjBL, there is no culminating test at the end. The project evolves as the main course , not the deser t at the end (3). Once a class starts the project phase, momentum sustains students’ focus and stamina until it is complete. The advantage of PjBL is that students learn self-directed problem solving on meaningful real-world projects (4). In practice, when the DQ is presented at the start, an evaluation rubric (ER) is also provided that briefly describes the evaluation criteria. This gives the student a clear understand of expectations from the beginning. Experience has shown that one of the most challenging parts for teachers is writing driving questions that engage students interest, is open-ended so it cannot simply be Googled, and aligned with learning goals (30). I am guessing that when Arduino is involved, a new challenge is being able to transfer enough starting knowledge in the focus activities for beginning students to head off independently. Some thoughts on that in Step 5 and 6 below.

Step 2: Role of the Scientific Method and Engineering Design Process in PjBL

PjBL is a learning methodology that can be widely applied to any classroom subject (1). But different subjects require different both different focus activities and application methods. For example history versus science. A review of online articles about PjBL in teaching STEM, robotics, and engineering classes, shows the application of either the Scientific Method (SM) or the Engineering Design Process (EDP) (5-7). But the selection rationale is seldom mentioned. I'm guessing many students are taught the scientific method in lower grade classes, so a shift to the EDP may be confusing. The reality is that both processes usually play a role in complex PjBL STEM projects. Scientists traditionally do research to discover new scientific theories. They use the scientific method to test the validity of those theories. Engineers use the scientific method when searching for known solutions. Likewise, the research that students perform in PjBL is not focused on discovering new theories, it is focused on locating known solutions or chunks of helpful knowledge that may support solving the Driving Question (DQ). That research (R) is followed by testing (T) to determine if the hypothetical solution/knowledge is applicable. Then, new applicable solutions and knowledge discovered in this research iteration can be combined with previously available resources, and made available to the EDP. The role of the EDP is to apply creative problem solving to design (D) a prototype solution to the DP from the collective knowledge chunks, then test (T) if the design produces an acceptable result, or if not, to iteratively trigger more research and redesign. Clarification of this staging of research and design may help students pursue their own problem solving challenges.

Step 3: A Template for Arduino PjBL Projects

The above perspective on the role of SM and EDP is helpful to understand their staging overall in STEM PjBL. A project starts with a description of the Driving Question (DQ) and an Evaluation Rubric (ER), followed by a relatively short sequence of key Focus Activity (FA#) lessons to provide initial scaffolding. For Arduino applications, these would be the basics needed for Arduino module construction (more about this in Section 4). Next, the students dive into the project, doing student-driven research (R#) to fill one or more knowledge gaps, and test (t#) if they have an applicable connection. Once the students feel that the combination of the Focus Activity (FA) knowledge, along with the knowledge chunks from applicable research (R) combines to form an acceptable solution to the DP+AR, the students can make a decision to create a prototype solution (p#), and test (t#) the trial prototype, it not matching, they iteratively return to do more research, prototyping, and testing until a satisfactory product artifact is created (*P*). The sequence of activities will look like something this:

{DQ+ER}, FA1, FA2} --> {R1, R2, >p1-t1} -->R3 >p2-t2} --> *P*

which demonstrates learning to create {FA1, FA2, R1, R2, R3} = (DQ+ER} Bingo!!

A generalized template of this model for STEM PjBL is shown in the figure above. Obviously, students don't have to see this description, but this and other overviews (27), may be helpful structured guidance for teacher's.

Step 4: STEM+Arduino Success Background

A review of STEM success stories shows Arduino's simplicity, application flexibility, and affordability have made Arduino an excellent platform for use in STEM education (8). Teachers with little previous interest or background in engineering or computer science can learn to use Arduino in short seminars or online classes and instruct students to build engaging projects without dwelling into complex programming and electronics.

Arduino is a low-cost microcomputer board designed as a project at the Interaction Design Institute in Italy in 2005. The aim was to provide a low-cost and easy way for novice students to create devices that interact with their environment using sensors and actuators. Because of its simplicity, availability, and cost under $30, Arduino spawned an international DIY and Maker revolution with about 30 million active students, hobbyists, designers, and engineers, many with no previous electronics experience (Wikipedia). Today Arduino has a very mature ecosystem of training, reference material, and open-source hardware suppliers with hundreds of supported microcomputer boards, shields, modules, software libraries, and software tools.

Arduino training is now widely available. It universally follows the same curriculum, taught by the didactic method, that involves following instructions to building a core set of 5-8 modules. These consist of typing in a pre-designed set of software instructions, called a sketch, into the Arduino Integrated Development Environment (IDE) running on a laptop, downloading the software to the Arduino hardware board, exactly following instructions to build corresponding hardware on a breadboard board, connecting the Arduino to the breadboard and watching the module perform a given function. The core set typically includes at least the following:

• Blink an LED
• Use a push-button switch to control options
• Detect objects, such as a line on the floor, with IR obstacle sensor
• Measure distances with an ultrasonic distance sensor
• Control motion with a servo motion actuator
• Measure temperature or light level with an analog sensor
• Produce musical tones with a piezo buzzer

The magic of Arduino is that after just finishing one class where you learn to follow the instructions to build the core set of modules, you have acquired enough basics understanding that you can follow the instructions to build literally hundreds of other modules with different sensors and actuators that are easily found online.

As a teacher, you have also learned enough that you can now re-teach the same set of magical capabilities to a class of beginner students. If you already know about STEM and PjBL, you should be off to a good start to include Arduino in your own PjBL-STEM-Arduino teaching. However, a review of online articles shows that integrating Arduino in PjBL has its challenges.

Step 5: Ready, Set, ....GO!

Breaking through the "Full Meal" project barrier

A review of a large number of articles about STEM classes shows many that include Arduino technology, but are using an didactic versus PjBL instruction methodology (9-12). The highest frequency are basic (non-PjBL) Arduino classes where teachers repeat a subset of the standard 5-8 module curriculum. This is probably adequate, in lower grade classes. The second most frequent example is when Arduino is applied in a focus area, such as building robots, or for environmental sensing. Those extensions are relatively straightforward, as they only require adding minor Focus Activity scaffolding about building one or two additional modules, such as a motor controller or water quality sensor.

Some attempts at PrBL-STEM-Arduino classes appear to be "desert-level" project attempts. These first, re-teach a set of basic modules, minus one, then add a one project module at the end. There are also some interesting hybrid models that mix conventional (non-Arduino) components (switches, batteries, light bulbs, etc.) with one or two Arduino components. All these early efforts are encouraging efforts to incorporate Arduino in PjBL, but could go farther. The few examples that are completely Arduino focused were found at the college level (13).

Based on the current excitement independently about Arduino technology and PjBL methodology in traditional STEM, it is curious why there are not more examples of integrated projects at the grade 7-12 level? From my background in problem-based projects, versus teaching experience, I see two issues with the standard curriculum that may hamper wider development.

First, to much time is spent learning the details of module construction (copying sketch, downloading, wiring, etc.) over and over on 8 modules. Once you have gained the experience of copying and downloading a sketch, and building the matching circuit breadboard, you really don't learn anything new from repeating the skill over and over 7 more times. You probably learn enough only doing it a couple of times. In PjBL, if your goal is to get students engaged in PjBL "need-to-know" research asap to find an unmentioned module, then finishing an unnecessary 4-7 modules is wasting time.

An alternative is to apply the PjBL Focus Activity concept to shorten the process and get students into self-directed research asap. This could be done by only covering the bare bones skills on a couple of key modules. One module could be an LED/Switch example to illustrate indicators and controls, and the basic sketch organization. The second module could be an analog sensor (e.g. light or temperature) plus an indicator (e.g. buzzer or LED) that requires learning about analog variables, and conditional and loop statements. But of those two selections could be customized by the instructor depending on learning goals and the driving question. Then a shortened Focus Activity list could include the following:

Shortened Arduino Focus Activities

• How to use the Arduino Integrated Development Environment (IDE) on their laptop (lots of YouTube help)
• Learn to download a pre-programmed sketch onto an Arduino board
• Learn basic electric circuit wiring and breadboard logic (use the suggest Instructable or an alternative)
• Build a module with an LED and pushbutton switch to learn basic sketch structure
• Build a module with a Light Sensor and a sketch with a conditional and loop statements

This list is enough to give students enough hands-on experience with entering code for a sketch into the Integrated Development Environment, how to download the Sketch from their laptop to the Arduino board, awareness of the sketch structure and key program logic, and wiring their breadboards. But it is also short enough that it can all be covered in a small number of classroom hours.

One way to still expose students to the full set of 5-8 modules is by showing them finished examples all at one time. This can broaden their sense of possibilities without consuming construction time. The instructor could build an "example board" that shows working examples of each module. An example is shown in the figure above. This board could expose students to the multiple functional capabilities so they can see the functionality in operation, but at warp-speed, and not requiring manual implementation.

Second, the traditional curriculum it does not provide exposure to enough modules. It is unrealistic to expect students to have enough background to produce an inspired original project after only seeing 8 independent examples. By comparison, there is a vast difference between the current model and the way training is done in other creative disciplines. Teaching art is a good example. Imagine a hypothetical PjBL beginner class in watercolor painting. The DQ could be to create realistic water color painting of an outdoor garden. Then start with focus activities to demonstrate the use of several brushes and color mixing. Also give the class 8 samples famous of water color paintings. Then, set them off to independently make a creative water color painting with fall colors. It is not likely the beginners will have much success. This is a frustrating problem because it seems in contradiction to the first issue about shortening the focus activities. While I don't think there is a simple solution, I'll offer some suggestions later in Step 9.

Step 6: Closing Some Gaps

Filling Gaps in Fundamentals

I've used the words "follow exactly" over and over. The problem is, if you make even the slightest mistake, like a wire inserted off by one small hole .1" on a breadboard, or a missing semicolon at the end of a line when you copy a sketch, your creation will not work. Unfortunately, it can take hours to debug the simplest mistake. This often leaves beginners trapped in a trial and error situation that can be frustrating and often lead to abandonment. This is not surprising. The current training assumes that you have this knowledge. Unfortunately, it is unreasonable for a typical teacher to have this background, so they will not be able to pass it along to students. Without that knowledge, even trying to copy the supplied diagrams of the circuit will almost always lead to at least one, or more, wiring problems. Then, without understanding the logic of breadboards and wiring, you will spend time doing trial and error attempts get your module to work. Seeint this gap, I put together another Instructable: Arduino: Filling Gaps for Project Based Learning and First Time Teachers . I cannot over emphasize the importance of gaining these usually untaught skills first. Leaving it up to trial and error is probably the major reason beginners give up before they get to the aHa moment of mastering Arduino. Once you fill this initial gap, students should be more successful with self-directed project completion.

Breaking the Complexity Barrier

While it is true you can now build hundreds of different modules, they each only perform one independent function. At the beginning you will be thrilled with a single cause-effect functionality, from the input from a single sensor to cause a single actuator output. But soon you or your students will get the bug to scale up your creations to have multiple sensors, actuators and functionality. Then you have a new problem. Software and hardware modules don't compose like Lego Blocks. Adding sketches and module designs together is not the same as knowing the three laws of arithmetic that lets you solve any arithmetic problem. Discovering this problem became the motivation for writing a second Instructable: Making Complicated Arduino Projects

Step 7: Let's Do It ...

We now have all the pieces to put together an Arduino-based STEM-PjBL example. This example is based on extending a popular project in traditional STEM classes, the construction of a Rube Goldberg device. Rube Goldberg was a cartoonist who was famous in the early 1900s for his depiction of extremely complicated inventions designed to complete simple tasks. The STEM projects involved using what they have learned about the six simple machines and conservation and transfer of energy (14, 15). A typical Defining Question was, "Can I use simple machines to make a Rube Goldberg device that does a simple task?" The simple tasks might be to turn on a light bulb, pop a balloon, water a plant, etc.

This can be easily modified to be the DA for an Arduino-focused PjBL project:

Can I use Arduino modules to create a Rube Goldberg device that demonstrates a simple task after reacting to its environment

Along that will be the following Evaluating Rubric:

• Use three or more different Arduino modules
• Reactive to environment changes
• Performs a simple task

A PjBL Project Template is shown above for a hypothetical project. The task in this project is to hit a hanging ping pong ball with a paddle when a person gets near the device. The student starts by doing research to find an Arduino module to move a small paddle. A candidate is to use a servo motor to swing a small paddle. The student has already learned about the ultrasonic sensor demonstrated in a Focus Activity and decides to use this to detect when an observer has approached near the device. This will require using a conditional statement and loop to detect the observer. The student then builds Prototype 1 to test if these two activities will work. Making the prototype will also include building a table-top platform to hold the hanging ball.

Once Prototype A was finished and tested successfully, the student realized that they need to sense when the ball is at rest so the servo will not try to hit the ball if already swinging from a previous hit. Doing research, the student decides to use an IR light beam sensor and LED to sense if the ball is not moving, centered at rest and ready to be hit again. The student then constructs Prototype B by building the IR module and adding it on the platform, then testing it to make sure it works.

Finally, after completing enough research and testing to be satisfied that prototypes A and B work, the student integrates everything together into the End Product Artifact and demonstrates it to the class. A pseudo-code description of the basic sketch is shown above.

Step 8: The RubeGoldberg Construction

Here is a greatly simplified pseudo-code overview of the software sketch for the final construction and a corresponding wiring diagram. Note that the actual sketch will actually take more than a full page of details of setting up variables, pin connections, etc., but pseudo code is like an outline that gives you a top level overview. The actual hardware implementation will also be more complex than the breadboard shown since the components have to physical positions to implement the device sequence.

Step 9: An Example Rube Goldberg Artifact

Two examples of completed Rube Goldberg projects are shown above. The first one matches the template. The second has several additional functionalities. This includes several LEDs that blink until someone approaches, then blink differently when the ball swings back and forth. It also has a two-line LCD display that shows the distance measured by the ultrasonic sensor of an approaching observer. A piezo buzzer is also added that plays a tune when an observer gets near.

Reviewing the simple Evaluating Rubric from Step 7:

• Use three or more different Arduino modules: Yes-Ultrasonic Sensor, IR Sensor, Servo, and LEDs
• Reactive to environment changes: Yes: Operation does not start until a person moves close
• Performs a simple task: Yes: Bats ping-pong ball with servo motion when person detected

A video of the second project is shown above.

A version of the Arduino sketch software for the more elaborate version is attached below.

Step 10: expanding the arduino example set.

As mentioned in Step 5, I believe a major weakness in applying Arduino technology in "full meal" PjBL projects is a severe lack of a broader collection of design examples, or archetypes, to inspire the creation of more interesting End Products. A key reason is that students are only exposed to a small number of Arduino module archetypes. Yes, you do learn about 5-8 modules, but, that is only a tiny sample of the possibilities. I think it is unreasonable to expect students to have enough background to produce an inspired original project after only seeing 8 independent examples.

It may sound like there is some magic to the set of 5-8 modules since the traditional STEM curriculum teaches about the set of seven simple machines (inclined plane, lever, wedge, wheel and axle, pulley, and screw). The magic in mechanical engineering is that that set of 6 modules can be used to build virtually any mechanical machine. But that principle doesn't apply in the Arduino universe. The set of 5-8 modules is not really a basic or essential prime factor set of Arduino modules. The selection of 5-8 was probably based on what the training developer used in their own limited set of personal projects. Many Arduino tutorial developers seem to have roots in car and robot projects, which frequently use the servos, motors, and IR sensors in the set of 5-8. While those do find their way into many projects that move (e.g., cars or arms), if you are doing an environmental project, you may need a particle sensor, or if designing a wearable fashion you may need a flex sensor that is never mentioned in the training materials.

If you learn the classic set of 5-8, you have only learned about a small number of potential modules. You have the key to open the door, but little vision of what's behind the door. Remembering Maslow's Law, "If the only tool you have is a hammer, you tend to see every problem being solved with a nail." In this case, you spent all the class time learning about 8 different hammers, while your problem only requires 4 nails, but you are out of time and clueless about the best way to solve the other 4 problems.

It is interesting to compare the current model to how training is done in other creative disciplines. Art is a good example. Imagine a hypothetical PjBL beginner class in watercolor painting. The DQ could be to use watercolors to create a realistic painting of an outdoor garden. Start with Focus Activities to demonstrate the use of several brushes and color mixing. Then give the class 8 samples famous of watercolor paintings. Then the students are to create a watercolor painting with fall colors. It is not likely the beginners will have much success.

The design aspect of the training in many disciplines includes extensive exposure to known classic examples. An example is in undergraduate computer science. It is common to have an entire semester class called Fundamental Algorithms. This covers basic and essential algorithms that form the building blocks of more complex algorithms. It is usually based on volume 1 of a famous set of five books by Don Knuth titled The Art of Computer Programming (16). Although this 600 page book was written several decades ago, it is still a timeless classic. Volume 3 spends an entire volume just explaining algorithms for searching and sorting.

I learned about another example from a friend that was trained as a master machinist in Sweden. He could make a watch starting from bare metal. Published in 1868, he had to study a compendium of 507 drawing of ingenious mechanisms that constitute complex machinery (17).

A third example is March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure , with over 2000 pages and used in undergraduate organic chemistry classes (18).

I think one of the first compendium examples I was exposed to as a kid was the manual that came with Erector Sets. This was first released in 1913 and included dozens of illustrations of the exciting things to build, like lift bridges, cars, drilling rigs, and the ultimate a giant robot. I know first-hand that robot project was the inspiration for a generation of today’s early robot company pioneers. 

Obviously, all these examples leave the meager set of 8 Arduino modules in the dust. Unfortunately, there is, as yet, no comparable collection for Arduino. I think this is partly because most authors are either expert in the computer science side or the mechanical side, but not both. Meantime, here are some of the best resources currently available:

• Arduino Cookbook, M. Margolis (19)
• Exploring Arduino, Jeremy Blum. (20)
• The Arduino web site: arduino.cc (21)

Here are some research resources that touch on the mechanical side:

• Mechanical Engineering for Makers: A Hands-on Guide to Designing and Making Physical Things (26)
• Make: Making Simple Robots. Kathy Ceceri (22)
• Invent to Learn. Sylvia Martinez. (23)
• T he Big Book of Maker Skills. Chris Hackett. (24)
• Launch: Using Design Thinking to Boost Creativity and Bring Out the Maker in Every Student. Spencer. (25)

While already pointed out how difficult it is to teach the "doing" of science and engineering for STEM in general because it involves blending of core ideas, concepts, and practices, I think adding Arduino to the mix makes it even harder, but potentially rewarding (27).

Step 11: Going Further Into PjBL-STEM-Arduino Projects

I hope that this Instructable will be helpful to teachers involved in applying Arduino microcomputers in PjBL. While I do not have years of teaching experience, I do have years of experience applying the scientific method and engineering design process in many successful projects. That experience gives me a different perspective on the challenges to make effective Arduino-based PjBL projects that I hope will help increase the success of teachers on new projects. I hope to refine this Instructable, so I would love to get feedback on corrections and improvements, particularly from teachers.

11 top Arduino projects

Develop your coding skills with these projects for a low-cost alternative to the Raspberry Pi

Arduino (known as Genuino outside of the US) is an open-source microcomputing platform similar to the Raspberry Pi and the BBC Micro Bit .

First introduced in 2005 with the stated aim of providing a low cost way for novices and professionals to create programmes and make computing devices, more than 700,000 Arduino boards have been sold to date.

If you're keen tinkerer, we've collected a selection of the best Arduino projects out there to help get you start on project to try, and goals to pursue.

For many of these projects, all you will need is the items found in the Arduino starter kit, which include:- An Arduino (aka Genuino) microcomputer- Jumper wires- Resistors- Breadboard- LEDs- Buttons

Some of the projects are straightforward, while other are more challenging and will require other items, but most of those can be found in the project guides themselves. For the beginners, let's start with the simple stuff.

Raspberry Pi: Top projects to try yourself

ByAlbert Gajak

A Croatian developer has created the opportunity for you to make your very own Arduino-powered mobile phone that will help you learn how to code something very, very special.

The "fully-functional" mobile phone doesn't just have to be used for making and taking calls and sending texts. It can also be used to play simple games, like Pong, Space Invaders and Snake. Sure, it's no Candy Crush Saga, but who doesn't love to be reminded of their first ever Nokia?

This highly customisable mobile also features a media player that you can customise to ONLY play cat videos if that's your thing, or perhaps you'd like to integrate some other app. It's pretty much possible with the MAKERphone. The package includes a colour screen, a microcontroller,DAC and electronic volume controller,8 individually programmable RGB LEDs, a SIM card, plus Wi-Fi and Bluetooth receivers.

Albert Gajak is raising funds to put his Arduino-powered mobile phone into production using Kickstarter. He's so far raised a mammoth 162,000, despite his target being 11,000. He wants to educate people how to code, plus the basics of electronics including what each component of your mobile phone does.You can buy the complete package from $99, which includes the hardware to build it and instructions to get you started with coding.

Remote control LED lighting

By Windows IoT

Activating an LED light isn't making a rocket car, but it is a great project for teaching you the basics of coding and material building that you can transfer to future projects. This project, by Microsoft's Windows IoT team, will get you to build a basic LED that can be remotely controlled to switch on/off from Window 8.1 or Windows 10. A download sample includes code for USB and Bluetooth connections. This is one of the most highly rated projects under the Easy' category on the Arduino website, too.

Electronic soundboard

By Lindsey Fox

For those that enjoy musical projects, coder and tinkerer Lindsey Fox has come with a fun way to turn your Arduino into an electronic keyboard. You'll need extra resistors, a buzzer and several tactile 6mm button switches. Fox's project is a work in progress, so you may need to adapt her coding steps. But this is a terrific example of the versatility of the Arduino community. Persevere and you'll be playing extracts of Bach concertos in no time.

Garage door opener

By Megunolink

For anyone who has a garage with a motorised door, this is a positive way to up your coding skills while giving your little microcomputer a practical use. Following this project, you'll use your Arduino, a relay box and a transistor to remotely instruct your garage door to open or close. No guidance for manual doors, unfortunately, which would be considerably more complex to apply safely.

Lightning Detector

By Runtime Projects

You read that correctly: this project explains how you can turn your Arduino into a lightning detector. Commercial lightning detectors cost thousands. So it's no small feat that Runtime Projects has come up with converting and coding the microcomputer into a home-made detector that they claim can detect lightning from approximately 10 to 20 kilometres away. Shocking stuff. Downloadable code is included with its project guide via GitHub.

Motorised security camera

Home security is a big issue for many today. Lindsey Fox was having problems with one of her home security cameras, which was not able to sweep its designated area. She came up with an innovative way to solve the problem by creating her own motorised camera from easy to purchase parts and an Arduino. Take a look at her project to see how you too can create motorised devices using your Arduino.

Smart air purifier system

Aaron Kow is out to prove you can make a smart IoT device without stumping up hundreds for Google's Nest thermostat. His smart air purifier works to clean up the indoor air, while also being environmentally friendly by turning itself off when it is not needed. Kow gives you a step-by-step breakdown of what you'll need and how to set it up.

Alcohol level tester

By Team Poltergeist

There are other reasons for creating a homemade breathalyser other than using it to check when colleagues and friends have reached their limit, right? Not according to Francesco Manetti and Simona Pira, which shows you how to turn your Arduino into an alcohol level testing unit. Affixing nine LEDs to a breadboard, the team explains how to code the device so the LEDs light up according to the alcohol concentration it detects.

Stair climbing robot

For Arduino owners looking for a project with added wow-factor, Jason Jaeger's stair climbing robot is just the thing. Originally built for a robotics stair climbing challenge, Jaeger's robot, known as Stair Bear, is capable of scaling steps with considerable confidence. His project guide is concise and clearly written. A perfect project for those keen to try their hand at robotics.

Wii Nunchuk servo controller

By Mark Tashiro

Mark Tashiro's Arduino-powered servo project feels a little like a solution in search of a problem. After all, a moveable servo joint without a lifting arm or some other kind of appendage is a bit useless. Still, this is plenty for a creative robotics tutor or enthusiastic tinkerer to get started with. Along with code from todbot, Tashiro explains how to use your old Wii Nunchuk controller as a manipulation input for the servo.

Arduino Simon Says game

By Technology Will Save Us

Here's a project that draws on your craft and intermediate coding skills: building a Simon Says game. This particular version of the game comes from Technology Will Save Us, and involves making your own electro dough'. You'll also need to download the CapSense Arduino Library, which you'll find a link to within. You'll fit a trio of LEDs, and the object of the game will be to repeat the LED light sequence.

Arduino retro handheld game console

By sy2002 / Museum of Electronic Games & Art

If you're familiar with the classic game Breakout or contemporary variants, such as Shatter and Peggle then this game console project will be for you. Lead creator sy2002 , with assistant from doubleflash and Iamags, built a fully fledged, and beautifully presented version of Breakout called TeleBall using Arduino, for the Museum of Electronic Games & Art. This project is for advanced users with a confident understanding of coding and some solid craft skills, too, as it involves creating the housing and testing the physical inputs. A serious challenge, but the finished article is stunning.

Want To Learn Arduino? Get Building With These Arduino Projects!

In this article, I cover the 30 best Arduino projects you need to build in 2024, including a range of cool Arduino project ideas for beginners and more advanced users.

One of the best ways to learn all about Arduino is to get hands-on with project-based learning.

But what can you do with Arduino projects in 2024? Honestly, I think the possibilities are nearly limitless! It all comes down to imagination!

Whether you’re intrigued by automation systems, robotics, or interactive art installations, Arduino projects enable all this and much, much more.

They’re also an excellent way to hone your electronics skills if you’re actively looking for jobs in IoT .

So, if you’re driven by a desire to innovate, have a passion for technology, or enjoy creating, let’s dive into some fun Arduino projects!

• What Is Arduino?

If you’re new to Arduino, you’re probably wondering, what exactly is Arduino?

Great question! Let me cover the basics before we dive into some easy Arduino projects!

Arduino is an open-source electronics platform consisting of easy-to-use hardware and software.

You'll often hear about Arduino and Raspberry Pi when it comes to microelectronics in 2024, but that's a discussion for another day.

An Arduino board is a programmable microcontroller that includes various inputs and outputs (I/O), like serial communication, digital inputs and outputs, and analog inputs.

This is very cool indeed and a far cry from the basic breadboards I used to learn about electronics during my undergraduate studies.

Arduino boards are typically used in a free and open-source development environment. Combining these allows you to write, upload, and execute code that controls your device, invention, or project.

One of the coolest ways to use Arduino is to get creative, whether you want to build a simple LED light device or are interested in IoT (Internet of Things) or robotics.

And if you’re just starting out, there’s a huge and active Arduino community that offers support, shares their own projects, and more. 

Of course, if you’re brand new to the world of Arduino and you’re not sure where to start, we’d definitely recommend complementing your projects with an Arduino course.

• What Skills Do You Need For Arduino Projects?

Let's set the record straight: you don’t need to be an expert to start working on Arduino projects! In fact, I genuinely think that Arduino projects can be great for all skill levels.

That said, you should probably have some basic skills before you get started, or at least be willing to learn them!

For example, Arduino projects usually involve C++ coding if you're building from scratch, so consider a C++ course if this sounds like fun, but you're not familiar with the language.

Let's take a look at the basics I think you should have to follow along with our Arduino projects:

• Basic programming knowledge: Even if you’re following along with someone else’s code, basic programming knowledge is useful for figuring out any issues that may come up.
• C or C++ skills: Arduino is based on C++, so it's really helpful to have C++ skills to create your own projects from scratch.
• Basic electronics knowledge: Arduino projects involve working with various electrical components, so it’s essential to understand the basics of current, voltage, and resistance.
• Ability to read schematics: Arduino projects often come with schematics that make them easy to replicate, so you’ll need to be able to read these to work with these kits or projects.

I should point out that it’s also really easy for complete beginners to pick up easy Arduino projects and learn these skills along the way.

But if you are feeling uncertain, I also think it helps to pick up an Arduino book for some extra help if you're brand new to the area.

I know from experience that it's always nice to have some reference materials on hand!

• Best Arduino Projects for Beginners in 2024

To get things started, I'll start with ten Arduino starter projects that are generally on the simpler side.

This means they require less time to put together, and they're also a great way to get a taste of what you can do with Arduino!

1. PC Info Panels

Download Source Code

Why We Chose This Project

First up on our list is one of the best beginner Arduino projects for newbies. I really like this as a gentle introduction, as you’ll use an Arduino Nano to interface between an LCD display and your computer’s USB port.

Once the electrical components are assembled, you can use open-source software called LCD Smartie to show different kinds of information on your LCD screen, including system stats like network utilization, CPU load, disk space, and more.

I also like that you can use your info panel to download RSS feeds or run other applications. Very cool!

2. Vintage Screensaver

This might be appealing to me because of the nostalgia, but if you're new to Arduino, simple projects like this vintage screensaver are a great way to start!

Inspired by 90s screensavers, you can get a healthy dose of 90s retro styling with the TVOUT and a Yourduino.

I also like that there are nine screensavers to choose from, making it a fun way to create an interesting decorative piece and even reuse an old CRT display.

Although you might need to dig around for a CRT display, as they're not very common anymore!

3. ArduSniffer

I really like this one, as it's a genuinely useful project! With the ArduSniffer, you can create a USB-powered gas detector with an LED display.

Sure, it does have more components than the first two projects on our list, but I want to gradually introduce you to more challenging projects as we work down the list.

That said, I think this is a great way to level up your skills. Plus, it's pretty affordable and offers detailed instructions.

4. Bluetooth Controlled RC Car

If you like remote-controlled cars (we’ve all had one at some point, right?!), you'll love this project, as it uses Bluetooth, an app on your phone, and an Arduino. 

I like that the instructions are pretty basic, as it makes it easy for you to put the car together and make it work.

But if you want to get creative, you can use a 3D printer (or printing service) to design a body for the car!

5. Stroboscope (Zoetrope)

A zoetrope , sometimes called a stroboscope, is a pre-film mechanical device that gives the illusion of animation or motion. I love this project, and it's great if you’re a cinema fan! 

To build this Arduino project, you can reuse a defunct Xbox 360 CD drive with a spindle motor to recreate this cool gadget.

You get all the instructions and source code you need in the instructable, making this a great way to create a short animation (or the illusion of one).

6. Portable Temp/Humidity Sensor with an LCD Display

I think this portable temperature and humidity sensor is a fun beginner Arduino project, as it's easy to understand really relatable.

This particular project uses an Arduino UNO R3, but you can use any 5V Arduino board you choose, and you can even purchase new parts or salvage some from your old projects.

The code, which was made using the Adafruit DHT library, is included in the instructions, and you can power your sensor using a power bank to display data in real time.

7. Simple Programmable Robotic Arm

Do you like robots? If the answer is yes, read on!

This is one of the best Arduino robot projects for beginners, as you'll create a simple and programmable servo arm using Arduino UNO and the Arduino IDE.

The robot arm itself uses buttons and potentiometers to record and play five programmed positions. 

I like that this can be powered by your computer’s USB port, but you can also use an external power supply if you ensure the servo can handle it.

It's easy to make the bot arm from readily available materials, and the code and circuit schematics are included.

8. Nano Piano

Do you fancy yourself as Beethoven or Bach? Just kidding, but if you like music, this is a cool Arduino project.

It is a beginner-friendly project with all the schematics and code you need to build a miniature piano with four keys using the Arduino Nano Every.

I also like that you can tailor the Nano Piano to your style by choosing your base (perf or protoboard) and deciding whether you want to create a housing with 3D printing!

9. Coin Sorter

Do you have pockets full of change you don't know what to do with? Maybe, maybe not! I mean, who uses real money anymore, right?!

That said, if you’ve ever wanted to sort your coins, this simple Arduino project might be one to try.

All you need is an Arduino UNO, a 16x2 display, and an infrared (IR) sensor to detect the differences between each coin, sending them through the appropriate hole.

I need to point out that it’s super important to follow the instructions as accurately as possible. This includes marking and cutting the sorting holes precisely and ensuring the slopes are appropriately angled.

You can even create a simple prototype from cardboard or 3D print a body for the sorter.

10. Blind Spot Monitoring System

Rounding out our list of projects for beginners, this is a really interesting Arduino project if you're intrigued by real-world microelectronics applications.

In fact, this project even takes its inspiration from the 2021 Mercedes Benz S-Class, which used ambient lighting to blink when a vehicle is detected in the blind spot. We've probably all seen these features in modern cars now, but it was revolutionary at the time.

In this case, we’ll be using an Arduino Uno and an RGB LED light strip to mimic the same thing. You can also set it to blink different colors depending on the position of the other vehicle relative to yours.

While there are many Arduino LED Projects to choose from, I really like this one as it's incredibly beginner-friendly and relatable.

• Cool Arduino Projects for Intermediate Users

Do you feel ready to take it to the next level? Let’s take a look at some intermediate-level projects!

11. Emotive Plant Pot

Ready for some more fun Arduino project ideas? Great, how do you feel about making an Emotive Plant Pot?

Now, let me take a second to say that this is not going to be Groot from Guardians of the Galaxy (I know!), but it's actually a 3D-printed plant pot with an LCD display that you can use to show cute faces.

You can even 3D print the components yourself with the included files. Just use the detailed instructions and schematics, and away you go!

12. Touch Interface Controlled Robotic Arm

We're back to robotics! If this is something you like, definitely check out this touch interface robotic arm.

All you need is an Arduino and any older Android phone to get started. I think this is also a cool way to get more mileage from older tech! 

Now, as you'd expect, this project is a little more complex, but the schematics and code are provided, and there’s even an assembly guide with a clear video to demonstrate the steps.

You can also 3D print the components yourself or use a 3D printing service with the provided files.

Note that creator Maurizio Miscio states you can contact him for the graphical interface app’s code.

13. Hidden Smart Bookshelf

This one just sounds cool, so I had to include it! The idea here is to create a Hidden Smart Home Bookshelf that you can use to conceal items within a cabinet or shelf that’s meant to look like a full bookshelf.

The creator has even included a very detailed video to cover the building and assembly process.

If you want to access the Arduino source code, head over to the creator’s GitHub , and you can either follow along exactly or make your own improvements.

I also think that if you have extra space, you could scale this up into a concealed closet or door!

14. Neopixel Cake

I think this is one of those super cool Arduino project ideas that you can use to make a splash at a party or special event.

Yep, you can make a uniquely memorable cake that uses flexible LED matrices and an Arduino.

The matrices themselves are embedded into the cake, then covered with fondant icing to allow light diffusion and a much better effect. Watch out Cake Boss!

I also found that you can even program cool light effects or text into the LED matrix so it can display whatever you want.

Just follow the detailed video demo and make sure you have a cake ready!

15. Automatic Humidifier

If you live somewhere hot and dry, you probably know all too well how important it is to have a humidifier.

Well, you can build your own now! I love this project to create an automatic humidifier, and it's straight from the Arduino Project Hub.

This project revolves around using a DHT11 temperature and humidity sensor to detect environmental humidity, and this can trigger the humidifier whenever the detected humidity is below a set level.

16. CNC Drawing Machine

This is another flashback for me to my undergraduate studies and the class I took in electronics and manufacturing.

The idea here with this Arduino project is to create a CNC (Computer Numerical Control) plotter out of an Arduino Nano board and two old DVD writers.

This is definitely another slightly old-school project, but I love the way it can be used to create 2D or 3D images on plain or smooth surfaces with an Arduino and a printing mechanism. 

17. 32-Band Audio Spectrum Visualizer Analyzer

This is another project for music lovers, as it's a cool Arduino project to create a 32-band audio or music frequency visualizer (also called an analyzer).

I found that this audio visualizer mixes signals from the left and right channels to ensure no beats are missed, and it also has five display modes that you can switch with the push of a button.

It's also cool that the audio feed can be taken from a line out or the headphone port of an amplifier or sound system!

18. Mind Control Drone

Now we’re not promising that this project will make you into the next Charles Xavier, but with a Mindwave Neurosky sensor and an Arduino, you can have a slice of this futuristic idea by building a mind control drone.

Let me make it super clear! This project doesn’t allow you to fly a drone with your mind, per se.

But you can control the drone’s liftoff and landing with your mind, which is pretty cool!

I think this is an awesome project for learning how to hack a PCB and control it digitally.

It’s also worth mentioning that the creator warns that you may mess up your drone and its controller when building this project, so be careful !

19. IoT Pet Feeder

If you’re looking for Arduino IoT Projects, this is a great choice, as you can build a smart food dispenser that can be controlled from your phone. 

I like these kinds of projects, as they're practical and great for enthusiasts who also want to pursue a career in electronics.

All you'll need to create it is an Arduino UNO, a servo, a PIR motion sensor, and a small speaker.

You can even adapt this project and turn it into an automatic bird or squirrel feeder for your backyard!

Feel free to set your smart pet feeder up any way you’d like, but the default instructions are designed to set the feeder to beep at a set interval. Then, when your pet investigates the sound, a PIR motion sensor triggers the servo to dispense food. 

If you’re a fan of Back to the Future, think of this as your own way to feed your very own Einstein!

20. Smart Dustbin

Rounding out our intermediate project list, this is a full project kit that you can use to create a hands-free, self-operating dustbin that's controlled with claps or foot taps. 

This is pretty cool and a great way to add some electronic magic to your ordinary household items. You’ll just need an audio sensor to detect your claps or taps.

The dustbin can also send IoT notifications to let users know when the bin is full, thanks to an ultrasonic sensor that detects garbage levels. 

• The Best Arduino Projects for Advanced Users

If you feel like your Arduino skills are at the expert level, or if you’re feeling adventurous, these advanced projects might be the right ones for you. Let’s take a look!

21. Star Tracker (Low Cost)

If you like looking into space, this is a great Arduino project, as it uses an equatorial mount to take pictures of the sky at night.

If you’re not 100% sure what that means, no problem!

An equatorial mount is a telescope mount that allows telescopes or cameras to follow the earth’s rotation, ensuring any long exposures come out clearly. 

I also found that this project creator claimed the Star Tracker is easier than putting together Ikea furniture and just about as affordable. What an endorsement!

Despite being an advanced project, the Star Tracker is relatively user-friendly, with all the requirements listed in the GitHub repo.

Be sure to share your photos with us after you build this project!

22. The Gaggiuino Coffee Machine

Do you like coffee? I have a strong suspicion that the answer is yes!

In that case, this is one of the best Arduino projects for you! But you don’t need to be an engineering student to give it an espresso shot (get it?). 

This project uses an Arduino or an STM32 Blackpill to create a “smart coffee” experience, where the end product is an aftermarket mod of many coffeemakers.

There’s even an active community around this mod, which you can find on their Discord server , along with videos from project users.

23. Automated Bean Sprouter

If you like the idea of self-sustainability and growing your own foods, you might be intrigued by this project! What's more, if you love bean sprouts, you have to try it!

The idea here is to build your own automated bean sprouter by using stacked trays, a rotating motor, and a watering system to keep your sprouts hydrated while helping air circulate and keep mold growth at bay. 

This is another super practical project that you can actually use in your daily life, which I really like.

The project page includes all the necessary information, including the component list, schematics, and code.

As an advanced project, it’s not the easiest, but you’ll never need to buy sprouts again!

24. UV Meter and Breathalyzer Keychain

This is a really interesting Arduino project that uses a UV sensor to create your own alcohol breathalyzer in the form of a keychain.

All you need to create this handy keychain is an Arduino Pro Mini 328 and an Arduino UNO (or FTDI). The keychain itself is powered by three 200mAh Li-ion batteries that you can recharge via the USB charging port.

To finish things off, you will use an OLED screen to display everything you need.

Detailed instructions are provided with this project, including 3D files so you can print the spherical casing yourself (or get it printed by a 3D printing service). 

25. Path Memorizing Robot

I like this project, as it's a classic for electronics students and anyone interested in self-driving cars.

You'll just need to use an Arduino Uno to control a little robotic car designed to navigate through a predefined path before returning to its starting point.

Before you create this path-memorizing robot, you’ll need to build a regular remote-controlled car using an IR receiver and remote.

But this is super easy if you follow the instructions and use all the provided code and schematics.

26. Arduino 3D Wire Bending Machine

I think this is a cool project if you like to be creative with industrial materials.

The idea here is to create an Arduino-based wire-bending machine that you can use to bend wires into all sorts of 3D designs.

You'll use an Arduino to control the motor and wire feeder movements, while a 3D-printed jig allows the machine to bend the wire into your desired shapes.

I also like that you can bend wire of varying shapes and diameters and adjust the radius and bending angle. 

This project itself involves mechanical, electrical, and computer engineering all in one, making it a fantastic choice for engineering students or professionals.

27. Camera Slider

Here, we have another cool Arduino project for photography enthusiasts.

In fact, if you've ever wanted to create cinematic shots with your camera, you might have considered a camera slider. Well, this is the project for you!

The plan here is to create a motorized slider for your camera that will allow you to achieve smooth movements and get cinematic shots.

You’ll need aluminum, a timing belt, and stepper motors, along with an Arduino to move the camera. You also need a rotary encoder that allows you to move the slider back and forth.

You can use practically any camera you want in this rig, as long as it can attach to the DSLR mount!

28. Self-Parking Car with Ultrasonic Sensor

Maybe you fancy yourself as the next competitor to Elon Musk’s Tesla?

Or maybe you just think self-parking cars sound cool?

Either way, I think this is a really fun build that allows you to create an advanced self-parking car via path-finding algorithms.

All you need to dois order the full kit, and you’ll be ready to get building!

29. LED Cube

We're getting close to the end of our list, and I thought it would be fun to include something cool to look at!

With this LED Cube project, you can build a complex LED cube with 512 LED lights, and this can be programmed to show cool lighting patterns and all sorts of effects.

I also really appreciate that the creator documents the building process in a YouTube video, making it easy for you to follow along. 

Schematics and code are all provided, so all you need to do is gather the components, and you’re ready to build!

30. Magnet Plant Levitation System

Here we are, the final Arduino project on my list!

And what a way to wrap things up, but with a super cool Arduino project that suspends a plant in mid-air by using the power of electromagnetic fields.

It honestly feels like science fiction, but nope, this really works! Just follow the tutorial, as it offers a detailed guide, including the STL files for the 3D-printed components.

I know the list of components required for this project is long, but I really think the end result is totally worth it to build a plant levitator!

10 Common Arduino Issues and How to Fix Them

Just after a few months of working on my projects, I started realizing that Arduino issues are a real thing, and I needed to find a solution as soon as possible. I couldn’t find a lot of answers on the internet, I had to learn them the hard way. So, I thought I’d share my learnings in the form of an article explaining 10 common Arduino issues and how to fix them.

The 10 most common Arduino issues are:

• Bootloader Problem
• Wrong Com Port
• Errors In Connection
• Outdated Drivers
• ESP32 Issue
• Arduino IDE Issue
• Serial Monitor Not Working
• Servo Problems
• Grounding Errors
• Programming Errors

While working on Arduino projects, I’ve learned how to deal with general hardware and software issues, which is one of the reasons why Arduino is worth learning . So, I’ll be sharing my personal experiences of dealing with the Arduino issues below, explaining the why and the tested solution for them.

What Are Some of The 10 Most Common Arduino Issues?

Arduino may seem like a piece of cake, but it’s much more than that. When it comes to errors, Arduino has a long list of them, which I’ll try to summarize by explaining just the 10 most common issues.

1. Bootloader Problem

The Arduino bootloader is a vital piece of code that allows the microcontroller board to read the program that is present in its memory when the board is turned on or after reset. The bootloader also enables you to change the program by writing and uploading a new one. It waits for an instruction from the Arduino software.

In case you have a bootloader problem, your Arduino won’t perform the above function, and neither will a new code upload to the board. The Arduino bootloader issue is one of the most common problems faced by beginner-level users as well as experienced Arduino hobbyists.

To solve this issue, you must first understand that the bootloader software, also called firmware , isn’t working anymore, meaning you need to replace the corrupted firmware with a new one. To replace the corrupted firmware, you’d need to download the Arduino bootloader file from the internet and upload it to the board.

For a detailed guide, visit this website . This article will guide you on how to deal with the most common bootloader issues.

2. Wrong COM Port

Another common Arduino issue that beginners face frequently is the Arduino COM Port issue. The Arduino COM Port issue happens when you’ve selected the wrong COM port in the Arduino IDE while your microcontroller board is present at some other port.

If this happens, you won’t be able to upload your program to the board. To avoid this issue, you need to get in the practice of checking your COM port when you connect the Arduino to your computer.

An Arduino COM port issue can also lead you to one of the most common problems, which is the “ not recognized” Arduino on your computer. You can see which COM port Arduino is present by checking the bottom right corner of the Arduino IDE screen.

The solution is straightforward; you need to check which COM port your Arduino is using. If the right port isn’t selected, then you can easily pick it through the Arduino IDE:

• Open the tools menu present on the top of the screen and hover your mouse over the “Ports” menu.
• You’ll see the name of your Arduino board along with the COM port that it is using.
• If you see a small tick beside your Arduino name, this means it’s present on the right port. If not, then select the correct COM port by clicking on it.

3. Errors In Connection

Another problem that many people go through is errors in connection, meaning there’s a problem in connecting the board to a computer. Using the wrong type of cable is one of the reasons why there’s an error in connection.

We tend to use our mobile charger as a USB cable for Arduino because it fits well, but the charging cable can’t transmit data. Charging cables don’t have data lines; hence you should invest in an original Arduino USB cable.

A connection issue can also pop up if the USB port of either your computer or your Arduino board is not working. Troubleshooting for this error is necessary because this is one of the reasons why your Arduino code won’t upload .

To solve the Arduino connection issue, you can buy an original Arduino USB cable, made especially for data transmission. Click here to buy one from the Arduino store. You can even find one from an electronics store near you.

Secondly, if your computer’s USB port is causing problems, then try connecting the Arduino board through another USB port. If that doesn’t help, try connecting it to another computer. If it connects, that means you need to get your computer’s USB ports fixed. If the USB jack on your Arduino board is faulty, then you can easily replace it.

I wrote a guide to the cables and wires you can typically expect to use with an Arduino. Check it out here: chipwired.com/arduino-cables-and-wires/

If you want to learn how to fix an Arduino USB port, check this article here .

4. Outdated Drivers

The drivers present in your computer are responsible for running external hardware devices such as I/O devices, printers, and Arduino boards. An Arduino driver issue is also a common problem. It occurs when the Arduino drivers present in your computer aren’t automatically updated, and your PC doesn’t recognize your Arduino board.

To fix the issue of outdated drivers:

• Go to the control panel, and click on the “Device Manager.”
• Then, find your Arduino’s USB port on that list. You won’t find your Arduino by its name because your computer does not recognize it.
• Right-click on the USB port where Arduino is present and click on “update drivers.”

If that doesn’t work, then to solve this Arduino driver issue, you’ll have to install them manually.

Click here to know how you can download an Arduino driver and install it on your computer.

5. ESP32 Issue

If you’re using an ESP32 module in your Arduino project, then brace yourself for encountering problems. Arduino ESP32 issue pops up when the IDE and your computer fail to recognize the ESP32 module. No matter what you do, you won’t be able to upload any piece of code, and this requires you to perform some basic troubleshooting if you want to get rid of this Arduino ESP32 issue.

Open the Arduino IDE and check whether you can see the ESP32 module over there (as in the image above). If it is present, then you need to click on it and select it. Otherwise, you’ll have to download the ESP32 add-on for Arduino. It will allow your computer to recognize the module.

Also, try pushing the reset module on your ESP32 device, this might make things work.

If you need to dive deep into finding a solution for the Arduino ESP32 issue, then click here .

6. Arduino IDE Issue

Sometimes, an Arduino IDE issue causes problems and doesn’t let you upload the program to the board.

How can you know if it’s an Arduino IDE issue that you’re facing? Well, if you get a “launch4j” error window popping up on the screen every time you click on something in the IDE, then you might be having an Arduino IDE issue. This error occurs because of a glitch in the backend of the Arduino IDE.

Arduino IDE is a java application, and launch4j is a java tool that allows apps to run in Windows OS. Sometimes, launch4j goes undetected by the Arduino IDE, and that’s where the problem starts.

The solution to this Arduino IDE issue is straightforward. All you need to do is restart your computer and relaunch the Arduino IDE. I’ve done this many times, and it quickly solves this problem.

7. Serial Monitor Not Working

A serial monitor is a tool that allows you to communicate between your computer and the Arduino board. You can send messages and read them using the serial monitor screen in the Arduino IDE. So, having an Arduino serial monitor issue means that the serial monitor won’t display any data. It won’t work, even though the Serial.print() and Serial.printIn() commands are present in the running program.

To fix the Arduino serial monitor issue, you need first to check the connections of your circuit. To make sure there are no incorrect connections and loose connections:

• Check the COM port in the Arduino IDE and make sure it’s the same at which your Arduino board is present.
• Check your code. Look at the serial commands. They can sometimes get blocked because of sitting inside an if-else statement, where the “else” condition never fulfills.

If the issue persists, try matching the baud rate of the serial monitor with that of the Arduino serial port. Usually, the baud rate is 9600, which works fine in serial communication. Matching the baud rate will solve the problem.

8. Servo Problems

To fix the Arduino servo issue, you need to provide a proper source of current to the servomotor. One way is to add a capacitor between the 5V and ground connections on the breadboard. The capacitor acts as a charge reservoir, supplying extra current to the servo to allow it to start without any hassle. Keep in mind that the capacitor must be of high value. Anything greater than 470 uF can solve the problem.

Another solution is to add an external power source for the servomotor. A common practice is to use batteries to power servos. Doing so will fulfill their high starting current requirements and save you from dealing with servo issues.

9. Grounding Errors

Grounding circuits is essential because it saves your project from unexpected power surges and damage. Grounding in Arduino can sometimes be an issue because the ground pin might refuse to work, or you’re not connecting it correctly. Whatever the case is, you need to fix any Arduino grounding issue as soon as possible to save your project circuitry from damage, like your board getting fried .

You can fix Arduino grounding issues by first checking the GND pin voltage using a voltmeter. Next, you can scrutinize the GND pin and see if there’s a loose connection, so you can solder it and fix it back into its place. You won’t experience grounding issues after you do this.

10. Programming Errors

There are several Arduino programming errors that can cause problems and delay your project. Most of the programming mistakes are pointed out by the compiler, but some of the minor ones go unnoticed, which is very annoying.

Here are some of the most common Arduino programming errors that the compiler doesn’t point out.

Equals and Comparison

If you’ve been programming your Arduino board lately, you’d know the difference between the equals “=” operator and the comparison “==” operator.

Using the two interchangeably isn’t an option because they have different roles. If by mistake, you type one “=” sign at a place where you had to compare two variables, your code won’t work the way it is supposed to, and you might never find out why your project is acting this way.

Float and Integer

Float and Integer are the standard data types used in C/C++ programming.

Floating-point numbers are those which contain a decimal, while integers, on the other hand, are whole numbers.

If your program is performing a mathematical calculation of dividing 20 by 6, the answer would be a decimal number (3.33). If you use an integer to store the answer to 20/6, then you’d get a ‘3’ instead of 3.33. The 0.33 difference seems like nothing, but if you need precision in your project, then this difference is going to be significant.

The compiler won’t count this mistake as an error, but it can cost you a lot by hindering the way your project works.

An array is a collection of values stored one after another. The size of an array tells you how many elements are present in it. For instance, if you have a variety of size 6, it means there are six elements in it. They can be numbers, strings, or alphabets. What’s important to note is the element numbering inside the array.

The counting always starts from 0 for arrays, which means if you have six elements, they go like 0, 1, 2, 3, 4, 5. If you want to access the first element of an array, it would be element 0, not 1. The last element of this array would be 5 and not 6, as many people mistakenly believe.

Many people make the mistake of not numbering the array elements correctly, which renders incorrect values when accessing the array.

To avoid these programming mistakes, you must always double-check your code before uploading it to the board because the compiler doesn’t catch the errors mentioned here; hence you need to keep your observation skills sharp and correct these mistakes.

Running your code with these mistakes will affect the performance of your project, and you wouldn’t easily find out what’s causing these problems.

• Always make sure to differentiate between the comparison and assignment operators. If you think you’re confused between them, you can always write them down on a sticky note and place it on your workstation.
• Also, store decimal values in a float variable and non-decimal values in the integer variable because this will increase the accuracy of your project.
• Furthermore, while working with arrays, remember that the element count starts from 0, not 1, as this will save you from facing problems in your code.

What’s Next?

I hope you’ve understood the possible causes of these 10 Common Arduino Issues and How to Fix Them. If you stay cautious of these problems in mind while working on your upcoming Arduino project, you’ll save a lot of time that you previously spent debugging errors.

I wish you all the best for your future Arduino projects. Happy coding!

Robotic Arduino Projects

As an Arduino enthusiast, I found making robots with Arduino to be most fun for me. There is so much to learn from them as a maker and an engineer. So, here are my Arduino projects related to robotics so you can learn too.

Arduino Robot Arm

When it comes to automated manufacturing, robot arms play big role with so many applications. They are often used for welding, assembling, packing, painting, pick and place tasks and much more. This Arduino project is actually a robotic arm made out of 3D printed parts, servo motors joints and controlled using an Arduino Nano. What’s even cooler we can control the robot arm wirelessly via a smartphone and a custom build Android application.

The robot arm has 5 degrees of freedom, so we need 5 servo motors, plus an additional servo for the gripper mechanism. For the communication with the smartphone we use the HC-05 Bluetooth module.

Difficulty: Intermediate

Mecanum Wheels Robot

The following project is one of the coolest Arduino project in this list. It’s an Arduino robot car which instead of normal wheels, it employs omnidirectional wheels or mecanum wheels which enable to robot to move in any direction.

The wheels are attached on four stepper motors which are individually control. By rotating the wheels in certain pattern, they exert diagonal forces due the diagonally positioned rollers on the circumference of the wheels, and so they can move in any direction. The robot car can be remotely controlled either vie Bluetooth communication and an custom build Android application. Also, we can control it using an DIY RC transmitter with the help of the NRF24L01 transceiver module.

Difficulty: Advanced

Arduino Robot Arm and Mecanum Wheels Platform Automatic Operation

Here’s an upgraded version of the previous mecanum wheels robot project. On top of the platform I added the DIY Arduino Robot Arm project mentioned above and now they can work together.

As the robot uses stepper motors for the wheels and servo motors for the robot arm, we can precisely control them using the custom build Android application. What’s even cooler, we can record the movements of the robot and then the robot can automatically repeat them.

Of course, as for any of my Arduino projects, the Arduino code, the custom build Android application, as well as the 3D model files can be found and downloaded from the particular project article.

SCARA Robot – 3D Printed

SCARA robot or Selective Compliance Articulated Robot Arm is the most common and suitable option, when it comes to pick and place and small assembly applications, which require moving a part from point A to point B.

This Arduino based SCARA robot is a step-up big compared to the previous projects in every aspect. It has a better and more robust design with precisely controlled stepper motors and custom build GUI for controlling it.

As a controller it has an Arduino UNO board, combined with a CNC shield and four A4988 stepper drivers. It has 4 DOF, driven by four NEMA 17 stepper motors.

Laser Engraving Robot

This and extension of the previous project or I converted my 3D Printed SCARA robot to work as a laser engraver robot. Instead of the gripper mechanism, here we are using a Laser module for engraving.

For controlling the robot we are using an Arduino Mega board in combination with a RAMPs board. This a popular combination used for 3D printing and it can be used for laser engraving machines as well. As for a firmware, we are using the Marlin 3D Printer firmware and the Repetier control software .

DIY Mars Perseverance Rover Replica

Inspired by the NASA Mars 2020 mission and the successful landing of the Mars Perseverance Rover on the plant Mars, I build a 3D printed functional replica of it. I designed this DIY 3D Printed Mars Rover in a way that it can be easily recreated by following the instructions in the tutorial.

The rover features a rocker-bogie suspension which allows the rover to run smoothly on uneven terrain, just like the real rover. It has six independently controlled DC motors for driving and four servos for steering, and it’s controlled using an Arduino MEGA board. There’s also an FPV camera located in the cameras unit of the rover which can by used for controlling the rover remotely. The remote control is done with the help of a cheap commercial RC transmitter and receiver.

Arduino Hexapod Robot

Making biologically inspired robots is very popular among engineering students. This Arduino project is all about it, we will build a hexapod robot which features six legs, a tail or abdomen, a head, antennas, mandibles and even functional eyes. All of this makes the robot look like an ant.

Each leg have three joints, and for each joint we need a servo motor . That means that we need total of 18 servos for this project, and additionally 3 servos for the head movements and 1 servo for the tail. The brain of the robot is an Arduino Mega. We need MEGA because it’s the only board that can control more than 12 servos using the Servo library.

I also designed a custom PCB which acts as an Arduino Mega Shield so we can easily attach all servo connects. We can control the ant robot via Bluetooth and a smartphone, or radio communication. The ant also has built-in ultrasonic sensor in the head. With that it can detect objects in front, and it can even strike if the object is present if front of it.

CNC Machines Arduino Projects

The following projects show how capable Arduino is. A CNC or Computer Numerical Control is an automated control of machines, like mills, lathes, plasma cutters, 3D printers and etc. So, using the Arduino as a controller we are actually able to build any of these CNC machines.

DIY Laser Engraving CNC Machine

For the project my goal was to build the simplest CNC machine with minimum parts possible and by using just a single power tool. On top of that, I wanted to use common materials or avoid 3D printers so I used MDF board for building the base frame.

The CNC machine is composed of just two linear rails which are secured to a base frame made of 8mm MDF board. For controlling it we are using an Arduino UNO board in combination with a CNC shield and two DRV8825 stepper drivers. As a tool it has an laser module attached so this machine is actually a CNC laser engraver.

DIY Pen Plotter with Automatic Tool Changer

A CNC drawing machine or a pen plotter based with automatic tool changer. An awesome way to draw anything in any color. 

The idea for this Arduino project was similar to the previous one, to build a CNC machine using minimum parts possible. Here I used 3D several printed parts, and just two MGN15H linear rails for the main construction of the machine.

Arduino CNC Foam Cutting Machine

Building your own CNC machine might seem like a big challenge for many of you, but the following Arduino CNC Machine project shows that building a CNC machine is actually not that hard.

This CNC machine is actually a foam cutting machine. Instead of bits or lasers, the main tool of this CNC machine is a hot wire. It’s a special type of resistance wire, which gets really hot when current passes through it.

The hot wire melts the foam when passing through, and so we can precisely make any shape out the styrofoam.

Link: Arduino CNC Foam Cutting Machine

Arduino Wire Bending Machine

Controlling stepper motors using Arduino is without a doubt one of most satisfying thing for an Arduino enthusiast. There so many machines based on this motors, like CNC machines, 3D printers, various automation machines etc. This Arduino project is all about that. It describes how you can build such a machine. It’s a machine for bending wire, where with the help of stepper motors we can precisely bend wire and make various shapes and forms out of it.

The machine features three stepper motors. With the first stepper we feed the wire to the bending mechanism. Here we have another stepper motor used for the bending the wire at the right angle. There’s also another stepper, for controlling the Z-axis. This stepper enables the machine to create three dimensional shapes. With this project we can also see how useful 3D printers are for Arduino projects of this type or for prototyping.

Radio Control (RC) Arduino Projects

Controlling Arduino projects using radio devices is quite useful and fun at the same time. I have made several radio based projects.

DIY Arduino based RC Transmitter

Many Arduino projects that I make require wireless control and that’s why I build this Arduino based wireless radio controller. With this RC transmitter I can wirelessly control pretty much with a range up to 700m in open space. It features 14 channels, 6 of which are analog and 8 digital inputs.

The brain of this Arduino project is an Arduino Pro Mini board which is the smallest Arduino board. The radio communication is based on the NRF24L01 module , it has 2 joysticks, 2 potentiometers and 4 momentary push buttons. Also an accelerometer and gyro module which can be used for controlling things with just moving around or tilting the controller. I mounted all electronic components on a custom design PCB and made a cover out of transparent acrylic.

DIY Arduino RC Receiver for RC Models and Arduino Projects

This is a follow up project of the above one. Just like DIY RC Transmitter, this DIY Arduino RC Receiver can be used for many application. We can easily pair the two projects together and control anything wirelessly. Among others, I made an example of controlling a commercial RC car model using these DIY transmitter and receiver.

The custom PCB that I made uses the same NRF24L01 module for the radio communication. The controller is an Arduino Pro Mini and it features input/ output 9 channels.

DIY Arduino based RC Hovercraft

The following Arduino project is a great example of utilizing the DIY RC transmitter from above. It’s a 3D printed hovercraft which I entirely designed on my own, and of course, the 3D printing files are available for downloading. The hovercraft uses two brushless motors , one for creating an air cushion for the lift, and the other for generating thrust or moving forward.

For the wireless control we are using the NRF24L01 module, which accepts the data coming from the RC transmitter. Then using the Arduino and two ESCs (Electronic Speed Controler) we control the BLDC motors speed . On the back side of the hovercraft there is also a servo for controlling the rudders, or for controlling the steering. I must say that driving this DIY hovercraft is so fun.

Arduino RC Airplane

Anyone who had a chance of playing around with some RC airplanes knows how cool and fun it is. It’s even cooler and more satisfying if you build the RC airplane on your own. The following project steps the satisfaction up even further, because here I will show you how to build your own RC airplane which is 100% DIY build. Also, we have a 100% DIY radio control system based on the Arduino.

The airplane is entirely made out of Styrofoam and what’s cooler, the shapes are made with the help of my DIY Arduino CNC Foam Cutting Machine , a project already mention above. The radio communication is based on the NRF24L01 transceiver modules. For that purpose, I used my DIY Arduino RC Transmitter and DIY Arduino RC Receiver .

Arduino Robot Car Wireless Control

This Arduino project is an extension to the previous one, and here we will learn how to wirelessly control the Arduino robot car.

You can choose one of the three different methods of wireless control explained in this project, or that’s the HC-05 Blueooth module , the NRF24L01 transceiver module and the HC-12 long range wireless module . Additionally you can learn how to make your own Android app for controlling the Arduino robot car.

Arduino Wireless Weather Station

This Arduino project idea is rather practical because it features indoor and outdoor temperature and humidity measurement. It is based on the DHT11/ DHT22 sensor , the NRF24L01 transceiver module for the wireless communication and the DS3231 RTC . For the display we can either use 16×2 character LCD or a 3.2 inches TFT touch screen .

The outdoor unit can be powered with batteries and the indoor unit with an AC adapter. The outdoor unit measures the temperature and the humidity and sends the values to the main indoor unit. Here these values are printed on the LCD along with the data and time values from the DS3231 RTC module.

Additionally, we can use SD Card module for storing the data onto Micro SD card .

Motors Control Arduino Projects

Controlling motors using Arduino is actually quite easy, and there are some many interesting projects with can make with Arduino and motors.

Arduino Camera Slider with Pan and Tilt Mechanism

Camera slider are great for capturing cinematic shots, and having pan and tilt system on top of it even further increase the possibility to capture better shots.  In this project I will show you how you can build your own one, which costs way less then one found in the stores and still you can get great and super-smooth shots.

The slider has three NEMA 17 stepper motors controlled via the A4988 stepper drivers  and the Arduino Nano board. Using a joystick we can control the pan and tilt movements and using a potentiometer we can control the sliding movement. With this DIY camera slider we can use the Set button to set two different IN and OUT points. Then the camera can automatically move from one to the other point.

DIY Vending Machine

If you are interested in building something more complex with Arduino then this project is the one for you. Although complex, you could easily recreate it as there is a detailed step by step explanation on how everything works, including circuit schematics and source codes.

The structure of the machine is made out of MDF. For discharging the items I used continuous rotation servo motors, while for the carrier system I used two NEMA17 stepper motors. For detecting the coins the machine uses an infrared proximity sensor.

DIY Arduino Gimbal / Self-Stabilizing Platform

The following Arduino project is a simple gimbal or a self-stabilizing platform. It can be used for keeping objects or the top platform level. The project is rather simple with just several electronic components.

Based on the MPU6050 orientation and its fused accelerometer and gyroscope data, we can control the 3 axes or servos that keep the platform level.

Link: DIY Arduino Gimbal | Self-Stabilizing Platform

Arduino Robot Car

The combination of DC motors and Arduino is always fun, and so is this project. Here we will build our own robot car from scratch. The car will be powered with Li-ion batteries and two 12V DC motors, and controlled using the L298N driver and an analog Joystick.

Through this project we will also learn how H-Bridge and PWM motor control work.

Link: L298N Motor Driver – Arduino Interface, How It Works, Codes, Schematics

Arduino Projects for Beginners

If you found the above projects a bit hard to start with, you can try the following projects which are good for beginners.

Arduino Radar (Sonar)

This is one of my most popular project and it’s really fun to build. The radar can detect objects in front of it and map them on PC screen using the Processing IDE .

For this project you just need two components along with an Arduino board, and that’s an ultrasonic sensor and small servo motor. The range of the radar can be adjusted to up to 4 meters with 180 degrees rotation.

Difficulty: Easy

Link: Arduino Radar Project

Range Measurer and Digital Spirit Level

Here’s another project utilizing the HC-SR04 ultrasonic sensor . This time we will use it to make an distance meter which can measure distances up to 4 meters, as well as, measure square area.

The project also includes and accelerometer which is used for the digital spirit level function or for measuring angle. The results are displayed on 16×2 LCD and all components are attached on a custom design PCB.

Link: Arduino Range Measurer and Digital Spirit Level Project

Arduino Color Sorter

Sorting out objects or products by their color has an important real world application. These types of machines are often used for sorting fruits, seeds, plastics etc. The working concept of these machines is rather simple. All you need is a color detecting sensor and of course a system that feeds the object to the sensor and then sort it out.

In this project we will learn how to use a color detecting sensor along with the Arduino . We are going to be sorting out colored skittles but you can use the same sensor and method for sorting out anything else.

Link: Arduino Color Sorter Project

RFID Access Control System

RFID technology has wide range of applications and access control is one of them. We often encounter this in hotels for accessing our room or at work for checking in or accessing restricted areas.

In this project we will learn how to use the Arduino to make an RFID controlled door lock . The system consists of an MFRC522 RFID reader and RFID tags/ cards that are based on the MIFARE protocol.

Link: How RFID Works and How To Make an Arduino based RFID Door Lock

Arduino Alarm System

If you ever thought of making your own security system then this project is a great starting point. Here we will utilize an ultrasonic sensor for detecting movement.

If a human or object passes in front of the sensor, the alarm will be activated. For deactivating the alarm you will have to enter a password using a keypad.

Link: Arduino Security and Alarm System Project

Arduino LED Matrix Scrolling Text

In this project we will control LED Matrices using the MAX7219 driver. This driver can control up to 64 individual LEDs while using only three wires. Also we can connect up to 8 drivers in series and still using the same wires.

To make this project more interesting I also added an example where you can update the text on the LED matrixes through your smartphone using a custom-made Android app .

Link: 8×8 LED Matrix MAX7219 Tutorial with Scrolling Text & Android Control via Bluetooth

Arduino Game Project

This game project is based on the popular Flappy Bird game for smartphones. Using the touch screen we control the bird while trying to avoid the pillars.

For this project we need a 3.2 inches TFT Touch screen , an TFT Mega shield adapter and an Arduino Mega board. The code is a bit longer but everything is explained in details.

Link: Arduino Game Project – Replica of Flappy Bird for Arduino

Arduino Music Player and Alarm Clock with Touch Screen

In this project we will learn how to build our own music player. It features a touch screen, MP3 player, a temperature sensor and an alarm clock.

The code behind this project is a bit more complex with around 550 lines but everything is explained in details with comments for each lines. There is also a detailed video explanation for it.

Arduino based interactive led coffee table.

At first glance this table looks like a normal coffee table but once you turn on the power on it gets to a whole new level. The table has 45 sections which can glow in any color we want, plus it reacts on objects placed on top of it.

The heart of the table is an Arduino which controls the 45  WS2812B Addressable LEDs . The objects on top of the table are detected using infrared proximity sensors. What’s even cooler it has built-in Bluetooth module which enables interaction with a smartphone for selecting the LEDs colors.

DIY Air Quality Monitor

Monitoring the indoor air quality is very important as it can affect us in many way. If we have a poor air quality in the room we are staying, it can lead to tiredness, headaches, loss of concentration, increased heart rate and so on.

In this Arduino project we are building an Air Quality Monitor which can measure several important air quality parameters such as PM2.5, CO2, VOC, Ozone, as well as temperature and humidity. I designed a custom PCB on which we can easily attach the sensors we need and show the results on a 2.8 inches touch display. The device can also keep track of the sensors values from the last 24 hours.

Arduino Projects Ideas

The following section of this article contains Arduino projects ideas based on my detailed tutorials on various sensors and modules, as well as your suggestions from the comments section below.

For each project idea I will point out the required components as well as the particular tutorial for each of them.

6-Axis Arduino Robot Arm with Cycloidal or Harmonic Drives as Joints

Building more robust Arduino based Robot arm which will employ either Cycloidal or Harmonic drives as joints.

Using my detailed tutorials how a cycloidal and a harmonic gearboxes work we can develop robotic joints which will have high torque and efficiency.

Cycloidal Drive working principle:

Harmonic Drive working principle:

We can use NEMA 17 or 23 stepper motors in combination with these drivers which provide high speed reduction ratios. As for controller we could use an Arduino Uno or Arduino MEGA board.

Android Smartphone Controlled Power Outlet Using Arduino

Controlling your home power outlets via a smartphone is the first step in home automation. You can easily make your own Arduino controlled power outlets utilizing the knowledge you can get from my Arduino tutorials.

For this project you just need two components along with the Arduino board. An HC-05 Bluetooth module and a 5V Relay module for which I already have detailed tutorials. For powering the Arduino and the relay you can use 220/ 110V AC to 5V DC converter.

Using your smartphone you can connect and control your power outlet via Bluetooth. You can either use some already made apps for controlling Arduino from the Play Store or create your own custom made app . In this way we can also control the power outlets through voice control commands.

Home Automation Arduino Projects

Home automation is one of the most popular Arduino projects nowadays. The goal of this project is to remotely control anything in your house like lights, appliances, temperature, security devices and so on, with a single device or your smartphone.

In order to make such a project we need decent amount of knowledge in Arduino. The following home automation concept that I suggest is based on my detailed Arduino tutorials for various sensors and modules.

So the idea here is to have a master unit which includes a touch display , and several slave units which will execute commands coming from the master. As for the wireless communication we can use the NRF24L01  radio frequency modules . Each slave unit can have various functions like, temperature monitoring , power outlet control , lights control, security alarm and so on.

Of course, there are endless possibilities and combinations for building a home automation system using the Arduino board. You can always change and add more devices. You can also make a Bluetooth communication so you can control all of this using your smartphone etc.

Arduino Gesture Control

The idea for this project is to remotely control an Arduino project using hand gestures. Let’s say we want to control the Arduino Robot Car that we mentioned above. So instead of the joystick we will use an MEMS module for the control.

We can use the GY-80 module which features an accelerometer, a gyroscope and a magnetometer . Then the data we are getting from these sensors to control the steering of the robot car. As for the wireless communication we can use the NRF24L01 transceiver modules.

You can also check my Mechatronics Final Year Project where I used a similar method for controlling a 3D model in Matab Simulink.

Feel free to ask any question in the comments section below and don’t forget to suggest some more Arduino projects.

44 thoughts on “The Best Arduino Projects – Robots, Sensors, RC, CNC and more”

I have not found a more comprehensive site for learning how to use an Arduino and make things with them as the brain. I also like that you can “understand what words are coming out of your mouth”(Chris Tucker and Jackie Chan reference). It makes things much simpler for me. I have a hard time understanding what many YouTubers are saying. I want to become a master of the Arduino quickly. I don’t have time to waste on sites with bits and pieces of information and many times with flat-out wrong information.

I am working on a project similar to your Home Automation using Arduino concept but using the HC-12 because the distance between remote units can be 600′ through trees etc. Basically its a property monitoring system rather than a home based system. Driveway monitor, human presence detection, temp in buildings etc. Your site and videos have given me the inspiration and confidence to give it a go. Thanks for the great content 🙂

Nice to hear it, have fun building! 😀

Hi, I am wondering if anyone has made an outdoor batttery powered wind chime “wobbler” to randomly make the chimes chime on windless days. I imaging a motor with a pulley and a sting attached to the paddle of the wind chime to simulate wind. Our neighbour has a really loud air conditioner and is now adding a pool pump. We would love to not listen to these sitting on our patio. I am an older person with no electrical or mechanical experience but am willing to try to learn.

Hello…I’d like to build an animatronic robot, (although it will closely resemble a talking/singing teddy bear). I need to build a control system that allows me to articulate the bear via custom joystick controllers. The signals will operate 12v relay banks which will engage air valves which in turn will operate pneumatic cylinders. Disneyland style, only on a much smaller scale. But I also need to be able to record the signal information in real time, and be able to make multiple passes during recording. (Example: record head tilt, ear wiggle, and eye movement on first pass…start at the begin again. Now as it plays back the movements I just did, I start operating mouth movement, arm and body movements. These would be recorded on another track. When played back…I have a bouncing talking and singing bear that operates on its on auto-pilot. Can Arduino products help me in any of the challenges that lay ahead for me? Thank you for any info. or thoughts you might have. 🛀Dave.

Hey, sure, you could definitely use an Arduino board as a controller. Depending on of the number of inputs and outputs you could use an Arduino UNO, NANO or MEGA. I’m not sure how much knowledge you have in this field, so I would suggest to check some of my tutorials. I have examples for controlling motors and sensors using custom design joystick controllers, so you might find those helpful. The project would have a lot of work, obviously, but I believe it would be quite interesting. Cheers and so have fun building one!

thanks a lot for share !!! its really amazing and great projects! Im just starting to understand this staff from Arduino I’m just a beginner so I need to ask you something about the different boards that you use: can I use a board bought in another online store for example aliexpress? and the other question is Will work your code with this board from aliexpress?

best regards, and again, thank so much for you help and incredible knowledge

Thanks! Sure, you could use mostly any board, bought from anywhere, which is Arduino based or compatible for any of these Arduino projects.

Make a dtmf car or drone

Firts of all let me thank you for all effort and very good explanation you put in your projects and videos, you already built a radio controller. Is there any future project to build an arduino based drone and control it throughyou RC controller? I guess ot would be very nice. Thanks again and congratulation for your good work.

Hey, thanks! Well yeah, I will build an Arduino based drone in some of my future videos, but I’m not sure exactly when I will do that. So stay tuned!

I’ve learned a lot from your website especially on how to control a device using a smartphone via bluetooth. Thanks man! You did a great job!

I’m glad to hear this, thanks!

Just want to say, great site, keep up the good work!

Hi Dejan, very nice work you doing here! Are you considering to build some battery project with as low power consumption as possible? Weather station would be a great example but you already built that. Maybe ver. 2.0? 😀

Thank you! Yeah, that’s a good suggestion and I definitely will make projects like that in future. A solar panels for charging can also be implemented.

First of all i really love this projects.

I want to ask to make CNC machine using old Inkjet Printer Parts, with DC motors and step readers on it..

Thank you. 🙂

Hey, thanks! Yeah, a CNC machine is already on my TO-DO list and I will definitely make one in future. 🙂

Excellent content and information…

Can you please tell me about the 5 volts external power supply(& how to build an another one for Arduino projects) you’ve used in your arduino projects for powering other actuators & devices

I would recommend to get a DC-DC Buck Converter which can be usually set to voltages from 3 to 35 volts, with inputs from 3 to 35 volts. And depending on your application you need to make sure that your buck converter have enough power, or it can handle the amount of current your project needs. Or of course, you can get a particular voltage DC adapter or power supply.

I would like to ask if you could do a tutorial on how to send strings from an android and print it on the computer via bluetooth module and using arduino.

Well check my Arduino Bluetooth tutorial. There I’ve explained how you can make communication between Android and Bluetooth module, as well as Arduino and PC.

How can I build a small cheap fall detection device that sends an alert to a phone when the wearer falls?

You could try to achieve that using an accelerometer sensor. If a sudden higher acceleration is detected that would mean that the wearer has fallen. Check my MEMS tutorial for this. These sensors are cheap and you might be able to get that effect.

Hey there i’m working on a project on metal detectors anything on the subject?

Hey, sorry at this moment I don’t have anything on that subject.

we are making a project about campus security system..how can we built a system that can lock or unlock door and record our data by scanning smartcard?

You should check my Arduino RFID Tutorial for that purpose. There I explain how to use RFID card to lock and unlock a door, and of course, you could add some more features to it, like recording the date, the time, count the data etc.

You have explained each and every project in detail and simple language. Anybody who knows the basics of electronic science can build the project easily and can enjoy Arduino circuits. Thanks to your team

I got an A in my project. Thanks for such beautifully designed website and arduino skills. Just a beginner at the moment. You rock! : )

That’s awesome! Thanks!

Wondering if your next project should be using a ESP8622, WS2812 strips and a TFT touch display. Many use the adruino webserver to control lights, but why not do it through a TFT to chose the various patterns and effects? Throw the phone aside and have a all in one to control those light!

Yeah, that would definitely be an interesting project.

i am a student working on my final year project which is to design an automated car jack,will use a hydraulic jack for lifting an automobile and i want to use my android phone to act as the remote control,meaning lift of the automobile will simply be done by just pressing the button in app which will be installed on my phone,kindly asking for some ideas on how i can achieve this and the necessary software/app i can use on my phone?

That’s a cool project idea. The main concern if you would like to build a real life example with lifting a car would probably be the lifting mechanism. Otherwise, if you just want to make the concept working with a simpler mechanism, the software/app part of this project would be easily achievable. For that purpose you can check my detailed tutorials, how to use the Arduino with the HC-05 Bluetooth module and how to make your own Android app for controlling the Arduino.

Hi, Shrikant here ,i was working on a project ,i got a problem in my project, the problem is,i am trying to operate big motors using relays ,contactor relay,operated by arduino. The relays does not operate properly ,the loop does not get completed .The relays are not taking load contactor ,i think so. It completed the loop 3 times only. Do you have any suggestion or hint please reply me.

Check my Arduino Relay Tutorial, it might be helpful.

are the relay coils providing a back emf spike as this may upset the arduino , this occurs when power has been interrupted to the coil the way to stop this is to wire a suitable diode in reverse polarity to the emf supplying the coil when it is to be activated , this may have already been done but I thought I’d mention it just in case

hi shrikant,

jst try to use regulated DC supply. If you are using 9v bat then same problem may occur.

The digital pins may not sink enough current to operate the relays, you may need to use transistors to switch the relays.

Dave is probably right but another way is to use a smaller relay and then pick the large relay with the contacts of the smaller one.

the arduino outlet current is very limmited at most 40m A for all pins toghether,which is means that if you directly connect your relay to arduino, it may damage your whole arduino or the least that pin connected to relay. its better to use optocoupler or transistor or both of them to seperate your high voltage or high current from your arduino. for optocoupler you may connect your arduin pin to optocoupler pin1(anode) ans resistor 330 or 470 ohm between them pin 2(cothode) of optocoupler to gnd pin 3(collector) to 5 or 12 or any voltage your relay work with pin 4(emmiter) to relay dont forget to use flywheel diod for your relay and for transistor arduino pin to base pin and a resistor between them collector to dc voltage emmiter to relay, again dont forget to use flyweel diod
