Nodemcu ESP8266 Power Supply Thanks for such high Quality PCBs.If we connect the solenoid lock to a relay (normally open mode): When relay is open, door is unlocked. We have to connect it to Arduino pin via a relay. Therefore, we CANNOT connect the solenoid lock directly to Arduino pin. Arduino Power Supply Module While working on any electronics based project you always need a power supply to power up your senso. The solenoid lock usually uses 12V, 24V or 48V power supply. ![]() Once tested that both are working, you can enter the master setting by entering the master. ![]() Then, move the servo back to the lock position, press the button or the keypads asterisk.
