Re: Fancy RGBish lights on robot/cart/etc

We have used an Arduino with the FastLED library to control lights.

Re: Fancy RGBish lights on robot/cart/etc

On our 2014 and 2015 robot, we had an arduino controlling the lights. In 2015 we completely redesigned our pit, working lots and lots of green LEDs that were the cheap, one-color ones. Those, we simply plug into an adapter which goes into an outlet.

One color LED strips are the easiest to work with. Simple outlet adapters like stated above work well in pits, and if you plan on using them on the robot, you can always use the 5V rail on the PDB and a few resisters. In my opinion, when used for aesthetic and not operational purposes, single color strips that you can just set in minutes is the best way to go. I have seen too many teams run into code, power, and design time issues simply trying to do a little much with LEDs. Yes, it's entirely legal and pretty cool when used correctly.

Re: Fancy RGBish lights on robot/cart/etc

On the robot, LEDs are legal as long as they conform to the other electronics rules. Last season, we used an Adafruit light strip connected to a Teensy LC (Arduino) communicating with the roboRIO over I2C. The LEDs would change color based on the alliance color, during autonomous, and when the robot took a shot.
