Relay Not Working at Virginia Barry blog

Relay Not Working. Make sure that the relay is not being asked to switch more current or voltage than it is rated for. Troubleshooting a relay can be done by following these general steps: Make sure that the relay is mounted in a secure location and is not exposed to excessive vibration or shock. Or to give the game away, the vcc on the relay module must connect to 5 v, not 3.3 v as the green led and the optocoupler are in series and require more than 3.3 v to operate. Try using a transistor to drive the relay coil rather. I'm using a small panasonic latching relay (p/n: If the relay is getting enough voltage, then the contacts are probably the issue, and you should get a new relay. Ah, good to know you've got it working. Verify that the circuit the relay is connected to is functioning properly. Check that the control circuit is providing the proper input to the relay. If it does not click, it may be. Can you try the relay without arduino? Check for proper voltage, current, and wiring connections.
