Specs from datasheet

3-in-1 LED. Red, Green Blue, or any other color formed by combining the colors. This can be done by pulsing individual color with PWM, or just switching it on and off using traditional ways (normal switch, or transistors).

This is the type of LED that's used in the previous post.

Nowadays, mood lights are getting common. How about making one?
