I'm using an Arduino Uno R3 to drive the LEDs in my Hyperion setup.
The Arduino also controls a relay, to power them on/off at the transformer to save power. The lights flash 3 times in acknowledgement (green for on and red for off) like car hazard lights do when you set the alarm.
This has been used on an RPi3 and a Vero4k, both running OSMC at the time.
The repo includes:
- The Arduino sketch
- The control program I use to send the on/off signals.
- Perhaps it should include a circuit diagram for the board/relay. But who has the time?

usage:
lights 0 (lights off)
lights 1 (light on)
