Hi all, I want to power my arduino uno without an adapter or battery. I am trying to connect to a host device that has a +12V out pin (which should be VERY consistent). Can I take that and plug it into the Vin port on the arduino? I also want to hook up a ps2 controller and I understand it needs +5…

How to power the board directly
