Northern Indiana | Trying to control this relay board with the pi. The board needs just a ground wire signal to activate relay. The pi will only produce like a 3-5volt signal. Is there anyway to make the pi send a ground signal? Or any other way.
This is for a Christmas light project my son is making and I wish I was more help!
