Christmas tree led strip plus ws2812 star controller

Here is a demo of 8 effects for the tree.

Some of the effects were modified from the sample code Adafruit NeoPixel RGBWstrandtest.

The LED controller is an Arduino Mega (but could easily be run on smaller hardware.) The string of LEDs is 300 lights and the end of the string goes into a ATtiny85, which is programmed to turn on/off an outlet that the Christmas star is plugged into.
