This is my RGB LED Christmas tree (it doesn't look really like a Christmas Tree), made out of a piece of transparent plastic sheet, a matrix board, a 3 x AA battery holder, and the brain of my ''design'', a PIC16F628A. I'm sorry because I didn't post it earrlier, but I was a bit busy with the Holiday preparations.
Anyway, this is my little toy in action. Hope you like it!
(Ignore the sound of the video, because I forgot the TV turned on while making the video)
