Level: Beginner
Time to Complete: 30 minutes - 1 hour
Skills Required: Soldering, SPIN Programming, Basic Mechanical Assembly, Breadboard Circuit Building.


The Parallax WS2812B REG LED Module is a whole lot of color in a tiny little package!  With its 24-bit color capability, you have more than 16 million colors to play around with. 

This project starts you off with the basics.  You'll learn how to make your LED display one of five programmed colors depending on the temperature recorded using your temperature sensor.  In this case, you'll see either Blue, Yellow, Green, Orange, or Red.
