In this tutorial, we demonstrate using an RGB LED to create various colors by mixing red, green, and blue light with an Arduino. We cover the setup, wiring, and code to control the RGB LED.

This series is possible thanks to the kind support of Sunfounder, an online store that sells high-quality hardware and kits for Makers. Visit Sunfounder at https://sunfounder.com.

In this series, I use the SunFounder 3 in 1 Ultimate Starter Kit with Original Arduino Uno R4 Minima, including high-quality sensors, actuators, power supplies, and Original Arduino Uno R4 Minima for diverse projects and skill-building.
