Arduino Projects for Kids

Arduino projects for kids can be a lot of fun. In this guide, we will answer some common questions and provide some useful tips to help you get started. Arduino is a popular platform for building DIY electronics projects, and it’s perfect for kids who want to learn about programming and robotics. We will show you how to set up your Arduino board and start coding!

Arduino in General

Arduino is an open-source platform used to create interactive objects and devices. It consists of both hardware and software components, the latter typically written in C or C++.

The name “Arduino” comes from the Italian word for “strong friend”, referencing a type of computer code that is easy for beginners to learn.

Arduino is a powerful and versatile tool, but it can also be intimidating for people who have never worked with it before. Fortunately, there are plenty of resources available to learn the basics and get started on your own projects.

Arduino in General

Arduino has a lot of benefits that make it a great choice for start-up projects or hobbyists. These include:

  • Low Cost: Since Arduino boards are open source and relatively basic, they typically have lower costs than other microcontroller options. This makes them an ideal choice for people on a tight budget who need to get their project up and running quickly.
  • Easy to Use: A lot of the components that are used with Arduino boards (such as sensors and motors) are plug-and-play, meaning you don’t need any special knowledge or skills to set them up. There’s also a wide range of both hardware and software libraries available that can be used to customize your project even further without needing to learn complex
  • It is an Open Source platform – Arduino software and hardware designs are open source, meaning anyone can study, modify, distribute and improve upon them. This means that it’s a great way to get involved in the exciting world of electronics without spending too much money.

Additionally, The Arduino IDE (Integrated Development Environment) makes programming easier by providing an intuitive interface where you can write code, compile it into machine language, upload it to the board and run it in real time. The IDE includes libraries that contain functions which are helpful when developing projects with specific components such as LCDs or servo motors. It also provides a framework for debugging code and troubleshooting errors in programming logic. [1]

Why Should Kids Learn Arduino?

There are many reasons why kids should learn Arduino. First and foremost, Arduino is a great way for children to build their problem-solving skills. Kids will experience the thrill of seeing immediate results from their hard work, as they watch the board light up or respond to whatever code they have written. Secondly, it allows them to explore various aspects of technology from coding and programming to soldering and pulling components together. Through these tasks they can understand how different parts of electronics interact with one another in order to create functioning devices.

Why Should Kids Learn Arduino?

Moreover, Arduino projects provide a fun way for kids to experiment with robotics and automation. They can learn how basic circuits work by controlling motors, lights or other components through commands sent over the USB port. [2]

At What Age Can Kids Start Arduino?

According to the official documentation, kids as young as 6 years old can begin to experiment with basic coding and wiring. The key is to start small and go slowly, allowing kids the time they need to learn the basics before diving into more complex projects. For example, a great first project could be making an LED blink when a button is pressed. This simple circuit will help them understand how code interacts with hardware in order for it to perform a function. As they gain confidence, they can move on to more complicated projects such as controlling motors or building robots.

With proper guidance from an adult or instructor, kids can also get involved in competitions and hackathons which focus on creating new devices or implementing innovative solutions. These competitions often require a more advanced level of knowledge, but they can also provide an amazing learning experience and help children build confidence in their skills. [2]

List of Arduino Projects For Kids

Now that you know a bit more about Arduino, it’s time to get your hands dirty. Here are some of the best projects and tutorials that you can use to help your kids learn Arduino!

Kids’ Toy Traffic Lights Arduino Project

The great thing about Arduino projects for kids is that they are not only fun, but also educational. What better way to learn about circuits, programming, and engineering than by creating a traffic light system using an Arduino board?

This project is suitable for children aged 8-12 and requires basic soldering skills. It involves connecting the components of the traffic lights to an Arduino Nano (or any compatible microcontroller), then writing and uploading code to control the operation of the lights.

Now for this project you will need: 5 mm LED: Green, Yellow and Red (four of each); 100 ohm resistor slide switch and rotary potentiometer.

You will also need some soldering job to do, this is best doing by an adult so that the children are kept safe.

To begin, construct a foundation for the battery pack and fasten the vertical tube. Next, connect the Arduino Nano Board to its power source. The Cat 5 cable distributes electricity and grounds the LED’s–and we only need to use only 7 of its 8 cores!

In addition to the Cat 5 cabling for our LEDs, we had to attach a battery pack with an inline switch and speed dial (Potentiometer). We are now finished with all of the wiring aside from that used for the LED’s.

To make the project look more aesthetic, hide the Arduino board and wires within an exterior case or a tube. Next, create the enclosures on LEDs and add the green, yellow and red LED lights. This can be done by either piercing or drilling three holes into the enclosures and attaching the LED’s. You should have four sides in total.

Then provide a CAT 5 with some support to hold the Arduino board and its components. This can be done with a wire of any kind. Secure the piece of glue firmly on the far side of your tube, making sure to create a slight bend so it descends along the interior.

After that, the programming can begin. This can be done using Arduino IDE and requires basic C++ coding skills or other related programming languages. The goal is to program the LED’s to turn on and off in sequences while also allowing it to react to an input (e.g., a switch).

Before linking the CAT 5 to the LED’s, we connected them in a series. This is similar to how they are linked together on a breadboard layout. Afterward, all of the negative ends were attached to their corresponding resistors and prepped with the ground wire from our CAT 5 cable for connection.

Finally, we connect the CAT to the LEDs. Glue the enclosure together and it’s time to code.

// green light minimum time, potentiometer set to minimum
int minGreenDelay = 5000;
// green light max time, potentiometer set to maximum
int maxGreenDelay = 10000;
// orange light wait time
int orangeDelay = 3000;
// time that both directions are red, before green starts
int redDelay = 1000;

// name pins for lights
int r1Pin = 2;
int o1Pin = 3;
int g1Pin = 4;
int r2Pin = 6;
int o2Pin = 7;
int g2Pin = 8;
// name the pin for potentiometer/speed input
int speedPin = A0;

no need to change anything below here

// set initial times for lights
unsigned long greenMillis = 0;
unsigned long orangeMillis = 0;
unsigned long redMillis = 0;
// set current direction
int currentDirection = 1;
// set the starting status – we set it green
bool greenStatus = true;
bool orangeStatus = false;
bool redStatus = false;

// start the setup
void setup() {
// initialise pins for leds as outputs
pinMode(r1Pin, OUTPUT);
pinMode(o1Pin, OUTPUT);
pinMode(g1Pin, OUTPUT);
pinMode(r2Pin, OUTPUT);
pinMode(o2Pin, OUTPUT);
pinMode(g2Pin, OUTPUT);
// turn on green light direction 1
digitalWrite(g1Pin, HIGH);
// turn on red light direction 2
digitalWrite(r2Pin, HIGH);

// start the loop
void loop() {
// read the potentiometer for speed
int sensorValue = analogRead(speedPin);
// delay 1 millisecond for reading/saving time
// calculate the delay using mapping
int greenDelay = map(sensorValue, 0, 1023, minGreenDelay, maxGreenDelay);
// store current time
unsigned long currentMillis = millis();

// if green time is reached and green is the current mode
if (currentMillis – greenMillis >= greenDelay && greenStatus == true) {
// set orange millis start time to current time
orangeMillis = millis();
// change to orange using function
// delay 4 milliseconds because of millis bug
// un set the green mode
greenStatus = false;
// set the current mode to orange
orangeStatus = true;

// if orange time is reached and orange is the current mode
if (currentMillis – orangeMillis >= orangeDelay && orangeStatus == true) {
// set red millis start time to current time
redMillis = millis();
// change to orange using function
// un set the orange mode
orangeStatus = false;
// set the current mode to red
redStatus = true;

// if red is on (both ways) then check the time and change to green other direction
if (currentMillis – redMillis >= redDelay && redStatus == true) {
// set green millis start time to current time
greenMillis = millis();
// change to green using function
redStatus = false;
// unset the red mode
greenStatus = true;
// change direction to the new direction
currentDirection = (currentDirection == 2) ? 1: 2;


// function to change to orange just needs current direction
void goOrange(int currentDirection){
if(currentDirection == 1)
digitalWrite(g1Pin, LOW);
digitalWrite(o1Pin, HIGH);
digitalWrite(g2Pin, LOW);
digitalWrite(o2Pin, HIGH);

// function to change to red just needs current direction
void goRed(int currentDirection){
if(currentDirection == 1)
digitalWrite(o1Pin, LOW);
digitalWrite(r1Pin, HIGH);
digitalWrite(o2Pin, LOW);
digitalWrite(r2Pin, HIGH);

// function to change to green just needs current direction
void goGreen(int currentDirection){
if(currentDirection == 1)
digitalWrite(r2Pin, LOW);
digitalWrite(g2Pin, HIGH);
digitalWrite(r1Pin, LOW);
digitalWrite(g1Pin, HIGH);

It takes some time and effort to get the traffic lights system up and running but it can be incredibly rewarding for children. Not only do they get to understand more about circuits, programming, engineering and so on but also gain useful skills that help them in their future studies as well.

Mini Piano Project

Another interesting Arduino project for kids is the mini piano project. To complete this project, you’ll first need to assemble an Arduino Uno board, a breadboard, seven 12mm push buttons, some jumper wires, and a piezo buzzer.

List of Arduino Projects For Kids

First of all, we start by connecting the push buttons to the Arduino board. Take the short leg of each push button and insert it into the breadboard in one column, leaving a few rows between them. Then take some jumper wires and connect each long leg to its own pin on the Arduino board. Make sure you label your pins clearly so that you won’t get confused later. Buttons should go from the pin D4 to the pin D10 of the Arduino.

The next thing you need to do is attach a buzzer to the Arduino board. To do this, take a jumper wire and connect it to pin D11.

The last step is to write a program in Arduino language that will turn each push button into a musical note. But before that, you will need to install a Tone Arduino library. You can easily find it at GitHub with a little of google search

Once you have the library installed, you can open up your Arduino IDE and start writing a program. The code should include a loop that will continuously check for button presses and if one is detected, it should play a corresponding note on the buzzer.

//Arduino Piano

#define T_C 262
#define T_D 294
#define T_E 330
#define T_F 349
#define T_G 392
#define T_A 440
#define T_B 493

const int C = 10;
const int D = 9;
const int E = 8;
const int F = 7;
const int G = 6;
const int A = 5;
const int B = 4;

const int Buzz = 11;
const int LED = 13;

void setup()
pinMode(LED, OUTPUT);
pinMode(C, INPUT);

pinMode(D, INPUT);

pinMode(E, INPUT);

pinMode(F, INPUT);

pinMode(G, INPUT);

pinMode(A, INPUT);

pinMode(B, INPUT);


void loop()
while(digitalRead(C) == LOW)

while(digitalRead(D) == LOW)

while(digitalRead(E) == LOW)

while(digitalRead(F) == LOW)

while(digitalRead(G) == LOW)

while(digitalRead(A) == LOW)

while(digitalRead(B) == LOW)



And that’s it! Now you can power your Arduino board and start playing some tunes. This mini piano project is a great way to introduce kids to the basics of programming and electronics. It’s also a fun way for them to explore music, as it gives them an opportunity to create their own unique melodies. [3], [4]
