DFrobot relay not providng power off the board
Account cancelled 2013-07-27 15:29:07 2267 Views1 Replies I have a DFrobot v2.1 relay board that I am using in an iPhone Garage Door opener project. I have the board set up but I dont have any voltage coming off the switches on the relay. When I use the iphone app, the indicated light on the relay lights up and I can hear the relay switching. when I push the manual relay switch button on the relay shield, the relay clicks and the light comes on. However i dont get an dc reading using a multimeter on either the NC connection or the connection at all.
Any recommendations, This is the situation for all 4 relays

2013-07-29 01:55:08 you should't get any readings.
the relay's just control the external circuit. You need to connect your circuit to your relay, and use the relay to break it. When the relay is ON it will let the electricity pass through (or OFF depending on your circuit )
NC stands for Not Connected, so forget about that one.
