12V door lock

Connecting raspberry pi to 12v electric lock

Ask QuestionAsked todayActive todayViewed 13 times1

I am trying to connect a 12V AC/DC lock to my Raspberry PI 3B+ so I can control it using python3 on the raspberry pi. Does anyone know anything I can do.

Here are my parts:

Aiden, the Pi is 3.3V, so on first glance the relay board may not work reliably. However the wiring should be straight forward, just do a search on raspberry pi gpio and relays.shareedit  follow  flag answered 2 hours agodave1111 bronze badge New contributor
