Arduino Tinkercad Project #3 – Control RGB LED Colors with a Potentiometer | Beginner Tutorial
Welcome to the third episode of my Arduino Tinkercad Projects series! In this beginner-friendly tutorial, I’ll guide you through using a potentiometer to change the color of an RGB LED in Tinkercad. Based on the analog input value (0–1023), we’ll divide ranges to display different colors—like red when the value is between 0 and 150, green between 151–500, blue above 500, and even more dynamic blends.
This project is perfect for computer programmers, tech beginners, and curious minds who want to build cool things without needing expensive hardware. Tinkercad lets you simulate everything online—100% free. Whether you're just starting with Arduino or expanding your coding logic, this project gives you practical experience with analog input and color control.
