[sudo-discuss] trying to troubleshoot door, but need a multimeter and don't know how to fix our battery-less one

read on if you have a multimeter to lend, or want to understand the door more: ==so-far== a wire came off the rpi gpio pinout. i looked in the code and realized that it is supposed to go to GPIO11, reattached it but still wasn't working, even though confrimed opendoor.py was being called then i shorted past the relay that gpio11 goes to and the door buzzed. we dont have a multimeter so i can confirm if gpio11 is going high, or the relay is burned out. can you help please?
