This way you can create animations on your computer/laptop which sends commands to the Arduino via Ethernet to animate the lights. This enables the Arduno microcontroller to communicate on your home computer's network. It should come with a USB Type B cable for connecting to your computer. It is a low-cost microcomputer (basic computer) that can be programmed to do almost anything. This is the "brain" of the light controller. Here is what you’ll need to build computerized, animated lights with Arduino: You can also visit my website for much more information on building computerized Christmas lights. You'll be amazed how easy it and have the best Christmas (and other holidays) lights on the block!

You can put lights into tube for glowing arches, attach them to strips to make virtual trees, and so much more. You can buy strings of lights to hang on a tree, or push the lights into "coro", a white plastic resembling cardbaord) in prepade shapes such as stars, candy canes, and more. This instructable will build one light controller than can animate up to 200 lights. You can do all of the wonderful animated lights that the professionals use, with a little bit of homemade building! The beauty is once you create multiple controllers as you add more lights to your house, xLights makes them all work together as a "show".

And the best part? Your lights are connected to your home wired or wireless network, so you can place your lights anywhere in the house or in the yard, controlled and animated from the comfort of your computer! The animations are created using the free xLights program. This controller animates strings of inexpensive lights found on Amazon, eBay, and lot of other online stores.

This instructable shows you how to build a low-cost light controller using an Arduino. Have you driving by houses with fancy Christmas lights, often synchronized to music? Normally, these setups require commercial light controllers costing hundreds of dollars, commercial animation software that can also be quite expensive, a literal money pit for the average home owner.
