Ep 047 - ASCOM Switch Compatible Arduino Power Box for Observatory Control
Running through the build of my power box which I will be using in my Observatory to control various 12V devices (dew heaters, camera power, etc)
My version of the firmware (factors for the inverted on/off of my relay board)

Relay Board used
I don't actually like this board, although it is cheap.
The active side is well specified and can handle the loads, but it requires 12V on the switching side also. In an ideal world, you would be able to power the switching side by the 5V supplied to the Arduino. My solution has the 12V powering BOTH sides, which is not ideal.

Wiring diagram
I found this wiring diagram to be most useful.
