Arduino powered door unlocker and secret knock detector

This project uses an arduino, wifly shield, servo, and piezo element to unlock your door from afar!

For our first Arduino project, we hacked together a wifi-enabled door lock with some nifty features. We used an Arduino and a WiFly shield, a modified servo motor, and a few other things.

The end product is pretty cool and has these features: - Unlock / Lock your door with your voice using Siri, an iPhone app, SMS, or a mobile web page (iphone app requires iOS developer account) - Monitor whether the door is locked or unlocked from far away - Get SMS messages when someone knocks on your door - Unlock your door with a secret knock (hard-coded for now)
