Do you want to control your garage door from your Droid-Phone? Here [hag] sent us his project that does exactly what your dream’s remote would do.

The GarageUino is my first Arduino project that has resulted in a product that I actually use. It’s a garage port controller that features a 20 by 4 character LCD display, four LEDs, a button, two connectors for position sensors and an USB connector. Oh! And of course an Ethernet port for Internet access.

On the [website] there is the full explanation, with pictures of the making process and the code for Arduino and the App for Android.
