My wife loves Halloween and I love electronics. This year I decided to spice up the tree a little bit some RGB LEDS. This was a neat little project that attracted quite a bit of attention from tricker-treaters. I had to inject power at 8 spots, for the 9 strands. One of the ten strands I ordered did not work out of the box so that is what I only used 9.
Here is a short video of one of the light routines.
