Christmas Light

I put up the Christmas lights today. They are four units. The first unit is some lights that move up to down like rain. The second unit has ten ornaments that are shaped like a Christmas tree, a reindeer, a bell, and a star. At the third unit, the strip is attached with LED lights that have over a hundred LEDs. The color of the LED light is changed randomly by a homemade system.
