total noobie here. I want to connect my pi board to a sainsmart 8 relay board. I've got the jumper wires. I cannot find(or don't know where to look for)the rest of the wiring diagram
I need to know which pins on my pi connect to which pins on the relay boards. I've got the 5v and ground worked out, but have no idea about the rest. If someone could point me in the right direction, I would be grateful.
