Overview
What makes the WS2812B really special is the way its controlled. The IC embedded into the LED communicates via a very unique one-wire interface. With the help of some libraries, they're really very easy to control. Plus they're chain-able -- the output of one LED can be connected to the input of another to create strips of hundreds of LEDs. The more boards you have linked together, the fancier your animations can be!
