1. I have a little air freshener that runs on 2 AA batteries. I was thinking about wiring it into a USB plug to plug into a port...That should work right? I have enver tried it before but thought this would be any idea.
2. I have some lights I want to hook up...I wanted to hook them into a distribution box. Is there a way if I use a relay that I can have them go to a block and then put a switch to it so the load is not handled on the wires going the switch and back?
