I'm trying to control a 12V electronic door strike lock from my 3V3 BeagleBone.
Here's a diagram of my circuit:
My circuit probably needs a NPN transisor of some sort, but I'm not sure which one would work. Also, because the strike lock is a solenoid, do I need any diodes/other protection in my circuit to prevent over-voltage/other bad things?
Thanks. Your help is much appreciated!
