With the prices dropping on LED strip lighting, setting up Permanent Holiday Lighting is getting more feasible every day. An Arduino makes a great DIY lighting controller.
For this project, I used some analog RGB LED Strips with a very simple Arduino control setup so we can make our own light show! I used two strips that were run next to each other, so there are six LED lines to control - two sets of R,G,B. The analog strips allow you to control each color for the whole strip so you can dim and brighten colors on the whole strip. Digital LED strips offer individual LED control so you can do chase effects, but they cost a lot more.
The setup for this is the same as was used for the TeleToyland Sandbox 2
project LEDs, except you can control those live!
