Using Red-Green-Blue (RGB) LEDs with Arduino (Common Cathode Type)

This tutorial covers the basics of RGB LEDs, focusing on the common cathode type. It explains how to connect an RGB LED to an Arduino, set up the circuit, and program the Arduino to control the LED's colors. The tutorial also introduces pulse width modulation (PWM) for color blending and demonstrates how to use a potentiometer for dynamic color control.

How do you use a potentiometer in conjunction with an RGB LED?

What is the purpose of mapping the input color value in the code?

How can you create different colors using the RGB LED?

What are some potential applications of using RGB LEDs in projects?
