“In this Instructable we’ll be creating a programmable RGB LED Christmas Tree and building the (X,Y) positions of the lights into the Arduino such that we can create different patterns both animated and static. I’d recommend this to anyone who has micro controller or electrical experience as it is a really impressive effect without much time to build up, and is much more affordable and capable then color changing systems you can purchase in retail stores. Even after creating the system and putting it into motion it is fun to add new patterns and color combinations to the tree. In my case the tree will cycle color patterns every minute.”
