Ever wanted to make that normal, golden star at the top of your Christmas tree different? How about color changing? The new Color Changing Christmas Star does that all in one package. The main components are 5 RGB LEDs, an Arduino UNO, and an Arduino Proto Shield. They all fit together on a Dremeled piece of plastic, then connected to a wire hanger covered with vellum paper. This makes a great new addition to every Christmas tree.
