About this project

This one is a follow-up to my previous Shift Register tutorial but, instead of using normal 5mm LEDs, we will use Common Anode RGB LEDs.

The wiring/connections are pretty much just the same. RGB LEDs just needs more resistors, jumper cables and breadboard space.

We will also use the ShiftPWM Library for some demos.

It uses SPI tho, so, I can't really elaborate that much on it, since I'm not that familiar with it.
