Wow, I like the idea of a room light sensor. I’m going to look into that. For someone who knows little about electrical I am fascinated with all that you can accomplish on a layout with it. After 30 years of waiting to start, I’m looking forward to a lot of years of learning.
If youre using self taping connectors with 22 or 24 awg wires, either 1) strip 2 wires, intertwine and open the connector a little to get 2 into the half-slot before you crip or 2) if you need a single wire then cut it a little longer and double it back on itself with the IDC before you crip.
