Its easy to hack up the addressable LED strip to an arduino and get it to blink following any of the tutorials on the web. (TODO link here)

In order to provide useful feedback to the drivers and spectators, the RoboRio will have to tell the arduino to change color or blink patterns. If only a few patterns are needed, we can select these by changing the state of one or more Digitial Output wires from the rio, connected to digital inputs on the arduino. If many complex patttern choices are needed, we'll change to a TTL or USB serial port for communication.

The LED strip can easily use more +5v power than the arduino can provide, so we'll use a DC regulator board to turn 12v from the PDP into plenty of +5v. This is a similar function to what the VRM does.

We'll mount the regulator board and some headers onto the arduino proto shield, so that it can all be plugged onto the top of the arduino Uno board. After wiring it all up, we'll design and 3d print an enclosure to protect the whole thing.

NOTE CHANGE from earlier: Do not connect regulator board +5v to arduino UNO +5v. It could backfeed into the USB connector when used for power and programming. Drawing has been updated

We power the arduino with robot battery voltage, and let its internal regulator and power switching handle it. Two series diodes drop the voltage of a fully-charged battery (13v) to below the arduino's maximum of 12v.

Caution: the arduino Uno and its proto board has power terminals marked +5v. Do not connect them to LED strip power or to the regulator board.
