Hacks and Mods: Open Your Garage Door Using A Smartphone


You do almost anything
with your mobile phone, but when it comes to your garage door, you have
to resort to another remote control. This garage door opener does not
require the installation of an application and it works with any phone
that has a web browser built-in. The system is based on the tux-graphics
Ethernet board.The circuit diagram has external connections, relay and
optional connection to switch to sense the state of the door. The relay
contacts are then to be connected in parallel to the wall mounted push
buttons inside your garage. They mounted the Ethernet board on a small
piece of wood together with some screw-on terminations for the cables.
