Doug384:
The easiest way to test these boards is to not use any Arduino at all.Get a 5v power supply, and first check that it is putting out 5 volts.
Then connect it properly to VCC and ground of the relay board, and (with the power jumper on) then take another (+) wire and try touching all the relay input pins one at a time. This should flip the relays on/off. If it doesn't, then something is wrong with the board.
Correction:"then take another" (-) not + "wire and try touching all the relay input pins one at a time." electricity only flows negative to positive. Not positive to positive.
