I love Chrismas Day, I think it's one of the best days in the year. We always make a nice Christmas tree with my family, but this year I decided that I'll add some extra function to this tree. Then I made a smartphone controlled light system. The best part is that you don't need to take apart your original light! The circuit controls a servo motor that simply pushes the button on the Chritsmass tree light.
