Different project NON Mirror related.
If you’re just interested in Arduino and led lights this one may be of interest.
This is a project that does require some planning to lay out wires, etc.
But what it does is gives me automatic lights without any other controls needed. The sun comes up the lights go out… turn on kitchen light the lights go out. I generally run most things through Home Assistant and you can this too but I didn’t feel it was necessary to do that. Just made them ‘automatic’ on their own.
