Making a plant sing has been a trick since the Theremin was invented. Here I am going to teach you how to do this with and arduino board, a gameduino shield and a the touch shield from my previous instructable.

Getting stuck out in the rain without keys was the motivation for this project. It lets you trigger a garage door opener through a website hosted by an Arduino. With the Arduino connected to a wireless network, you can use your smart phone to connect to the webserver, enter a password, activate the garage door and get inside before getting drenched in the downpour.
