Simple Arduino sketch, that turns on a pair of relay modules. I hacked this together to prevent over-loading the fuses when turning on the home cinema from the smart plug.

It waits a configurable amount of time (2 seconds), turns on power rail 1, waits 2 seconds, turns on power rail 2 and shuts itself off.

I embedded an Arduino Nano, a mini PSU and the relay module into a 2x5 port passive PDU.

This project involves mains voltage. Caution is advised!
