Multicolor (RGB) LED with Arduino PWM

This is the next step from our last post, where we take the single color example of PWM brightness control, and expand it to a RGB LED with a whole spectrum of color outputs. Instead of having one potentiometer, we

PWM LED Brightness Control

Pulse Width Modulation at last! In our last example, we read a potentiometer (pot) to get a analog value of 0-1023, and used that number to delay the digital on and off times of a LED. This example will do
