Arduino Potentiometer Tutorial | Build an LED Dimmer Switch (Tinkercad + Block Coding)
Learn how to use a potentiometer with an Arduino to create your very own LED dimmer switch! In this beginner-friendly tutorial, I'll show you how to control the brightness of an LED simply by turning a knob.We'll start by building and simulating our circuit in Tinkercad, using easy drag-and-drop block coding. Then, we'll take our code into the Arduino IDE, upload it to a real Arduino board, and test our working dimmer switch!
💡 **In this tutorial, you'll learn how to:**
- Identify the components needed for the project
- Connect a potentiometer and LED to an Arduino
- Build and simulate the circuit in Tinkercad
- Program the dimmer switch using block coding
- Transfer your code into the Arduino IDE
- Upload your program to a physical Arduino board
- Control LED brightness using a potentiometer
**Components needed:**
- Arduino Uno
- Potentiometer
- LED
- Resistor
- Breadboard
- Jumper wires
- USB cable
Perfect for beginners, students and teachers exploring Arduino electronics, circuits and coding!
