To do this he’s using a Bluetooth low energy breakout board coupled with an Arduino, two solenoid locks, and two capacitive sensors. He’s modified a pre-existing iPhone app to control the ...

He then hooked the wires up to a Bluetooth-enabled Arduino, and pressed buttons until he had all the serial commands the door lock used. After that it was a software game.

This kit uses a CD-ROM drive and an Arduino board to build a clever robotic lock. This dude used a bolt to create the project and it's voice activated.

Arduino enthusiasts may be interested in a new gesture controlled Arduino door lock which has been created by Adham Negm and uses an Arduino Uno together with a servo motor to slide the bolt back ...
