Electric imp based automatic door lock
|
|
Marcus built this automatic door lock for his office, which uses the Electric Imp and a RC servo to lock/unlock the door.
When we, PinMeTo, moved in to our office at MINC in the beginning of September we only had three keys to four persons and an extra key cost 500 sek so i built an automatic door lock for the door. Maybe cheaper to just buy an extra key but not as fun.
