# PDU power sequence
|
|
|
|
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.
