Arduino is an easy-to-use development board for hobbyists, tinkerers, and professionals. To build prototypes, for instance.
It’s probably the easiest way to learn microcontrollers these days. Therefore, many use it as a tool to teach kids about coding and electronics.
You can build projects like a robot or an automatic cat door. Even if you have no experience from before.
On this page, you’ll find a library of tutorials, projects, and other resources to help you get started and build cool Arduino projects on your own.
Here’s a cool Arduino project I did to bring a bit of high-tech magic to my daughter’s toy kitchen. She can now turn on the lights in her toy kitchen with a simple wave of her hand! My daughter has been excited about the thought of getting lights in her kitchen. And I was excited
Arduino libraries are like cheat sheets for building cool projects. They let you borrow code someone else made, so you don’t have to start from zero but can make your things quickly with your Arduino. Also, because lots of people use them, it’s easier to get help and tips. In this guide, you’ll learn how
In this tutorial, you’ll learn how to create an Arduino PIR Sensor. PIR stands for Passive InfraRed. The PIR sensor is widely used in motion detection applications and this project will show you how to use it to control an LED. When the sensor detects motion, the LED will turn on and the event will
In this tutorial, you will learn how to set up an infrared (IR) receiver with an Arduino UNO. An IR receiver is a module that will help you decode signals from an IR remote control. In this tutorial, we’ve used the TSOP312, but many others will work. The Arduino will process these signals and print
In this guide, you’ll learn how to set up an Arduino IR Transmitter circuit. It lets you control an IR (Infrared) LED and send any remote control code from your Arduino. This means you can use it to control your TV or anything else you feel like! This tutorial focuses on just setting up an
In this tutorial, you’ll learn how to interface an incremental rotary encoder with an Arduino to read the movement of the knob. This can be useful for creating user interfaces or reading mechanical positions in robotics and other applications. What You Will Need Schematic and Breadboard Setup Note that in this schematic I’m using a
In this Arduino motor guide, you’ll learn how to drive and control the speed of a DC motor using an Arduino UNO and a TIP120 transistor. In this example, you’ll use a pushbutton to ramp up the motor speed and then slow it down, thanks to the power of Pulse Width Modulation (PWM). Materials Needed:
In this Arduino servo motor tutorial, you’ll learn how to control a servo motor using an Arduino UNO board and a potentiometer. As soon as you’ve got this example project up and running, you’ll have the skill of controlling servo motors from your Arduino. This can be the basis for more advanced robotics projects. Components
In this guide, you’ll learn how to set up an Arduino Hall effect sensor, specifically the US1881, to detect magnetic fields. This can be useful for projects where you need to find the RPM of a motor or other movements in a machine. Parts Needed Schematic Diagram Connect the VDD pin of the US1881 Hall
A popular Arduino Ultrasonic Sensor is the HC-SR04. It’s widely used for non-contact distance measurements and often used in robotics and automation projects. This guide will show you how to connect an HC-SR04 to an Arduino and write a simple program to measure distance. Requirements Connection Diagram Step-by-Step Guide Arduino Ultrasonic Example Code Copy and
In this tutorial, you’ll learn how to connect an Arduino sound sensor to control an LED with sound. By the end of this guide, you’ll have a working sound-activated LED! Parts List How To Connect the Arduino Sound Sensor In the schematic diagram below, you can see the complete connections for this project. Connect the
In this beginner-friendly tutorial, you’ll learn how to set up an Arduino Speaker circuit where you will play a melody from your Arduino. By the end, you’ll have a basic understanding of how to create Arduino projects that play melodies.
In this quickstart tutorial, you’ll learn how to control a passive buzzer using your Arduino UNO to play a simple melody. By the end, you’ll have a basic understanding of how to incorporate sound into your Arduino projects.

In this guide, you’ll learn how to control an RGB LED using the Arduino. An RGB (Red-Green-Blue) LED can produce a wide variety of colors by mixing different intensities of red, green, and blue light. You’ll learn to create a basic Arduino RGB LED circuit and cycle through some basic colors as an example.
Using the provided schematic and breadboard images, as well as the example code below, you should have everything you need to easily set up and control an RGB LED’s color output on your own.
There are two types of RGB LEDs: Common Anode and Common Cathode. We’ll provide example schematics and code for both types below.
