Re: LEDs
We use an arduino to control our programmable RGB LED's we purchased from Adafruit, which you can easily get from ebay or amazon. Though you do need to add the 12v to 5vdc converter to run them.
For most of our LED needs we use a few sets we purchased from Costco. they can be strung together so you can make the set as long or short as you need. All we had to do is cut the power adapter cable and wire it directly to the PD board. They are 12vdc so nothing is needed to use them. They have an IR control for the colors and intensity. Just make sure you put in a way to cover the IR receiver so you cannot have "control" while it is on the field. We used a few pieces of Velcro. Holds it in place and just a quick removal to change to colors or turn on the disco light show.
If you have any question on how to implement any of the mentioned systems send me a PM and I happy to help.
Aloha
