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.

This request is sent to the Imp Agent in the Electric Imp cloud that is specifically associated with your Electric Imp. The Agent code is a mini Web Server that parses the request and if valid, passes it on to your Imp firmware via the cloud. This behind the scenes communication between the server based Agent and the hardware based firmware was developed by the talented people over at Electric Imp. Read More
