Raspberry Pi Garage Door Automation

Like many of us, [Felix] sometimes wonders if he actually closed the garage door. I know I’m always double-checking my car locks! So, he decided to automate his garage door to give him some peace of mind!
He’s been working on a pretty big Raspberry Pi home automation series, and in this final segment he shows off his new GarageMote board which, as you can guess, lets him wirelessly control the door. It’s a very simple board complete with a small relay, a diode, and 2 resistors. The 8 pin header provides connection to two hall effect sensors that detect the status of the garage door, and the original door opener. He then connects this to an open-source wireless Arduino clone of his own design, dubbed the Moteino. A pair of these communicate to the Raspberry Pi which acts as his secure home automation gateway server.
The whole project is extremely slick, and very well documented – so if you’re looking at automating your home, [Felix] has a wealth of knowledge to share — well at least if you want to use is Raspberry Pi!
Stick around after the break to see the web-server controlled garage door in action.
