Arduino Relay Won't Turn Off. when the program starts the relay is off, as it detects motion it turns on, but it doesn't turn off, even if no motion is. the relay won't turn off anymore because the first time you tried to turn it off, the flyback voltage generated by the relay coil blew out the transistor so that it is now. learn how to use a relay to turn on/off devices that use high voltage or current, such as a light bulb, fan, or electromagnetic lock. I'm unable to give you guys the picture, but the. the problem is, the relay won't switch and i was wondering whether its the program issue or hardware issue. Follow the step by step instructions, wiring diagram and arduino sketch to interface a relay. an arduino with 3.3volt logic outputs 0volt or 3.3volt on pin 10 (not 0 or 5volt). Some relay modules work with 3.3volt logic, others don't. assuming it's like my relays, that relay can either power the relay coils and the logic inputs, or (if you remove the jumper) use separate power for the relay coils and the logic. learn how to control a dc circuit using a relay and arduino.
