In this video I go over how easy it is to get a pixel strip running on Arduino. I use the WS2812B or also known as NeoPixel. I show using the Adafruit library and Pololuled library.
The Pololuled library can be downloaded here: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=11&cad=rja&uact=8&ved=2ahUKEwiAlprg3aPmAhUFTawKHUvgA3oQFjAKegQIERAB&url=https%3A%2F%2Fgithub.com%2Fpololu%2Fpololu-led-strip-arduino&usg=AOvVaw33Z8onFRzpMWagohhUkGTD
