A very popular type of LED that has finally come about is the tri-color, RGB LED. The RGB stands for: red, green and blue since the LED is capable of displaying all three colors, independently. This means that an RGB LED can display any color of the rainbow. This is a powerful capability, but it also requires more control.

In this article, we shall look at how to build an RGB LED controller so that we have accurate and independant control over all three colors at any instant. The method of Fading LEDs via PWM will be leveraged for this design, since our goal here is quite similar, but with more control paths.
