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.
