Thanks to everyone who supported this project and voted for it in the Arduino Challenge! I was awarded second prize and hope to participate in more Arduino contests in the near future. This tutorial will explain a simple way to make a password protected bluetooth door lock using your Arduino, which can be unlocked by sending a four digit pin from your Android phone!  The hardware setup is quite simple,  and the programming side of it is a bit tricky, but should be no problem for any Arduino ameuture.Step 1: Parts NeededShow All Items« PreviousNext »View All Steps Download ***Updated 8/9/2010*** I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 arduino chip and a ID-20 RFID reader to control an electronic door lock. The circuit consists of 3 separate parts, a Reader to read RFID tags, a Controller to accept data from the reader and control the output of the RGB LED and the Electric door lock.

The door lock is first installed in a door and tested with a 9v battery to ensure correct installation. In most cases you want a Normally Open circuit on the door lock, or Fail Secure. This means the door stays locked when no current passes through it. When 12vDC is passed through the electromagnet in the door lock, a plate in the lock gives way and allows the door to be pushed open freely. The reader is placed on the outside of the door and is separate from the controller on the inside so that no one can circumvent the security by breaking open the Reader and trying to short circuit the reader. The controller receives serial data from the Reader and controls the RGB led and the Door lock. In this case I have put both on separate bread boards for testing. Here is a video overview of the system in action Read on to see how to build one for your self! **Update**  All of the code, schematics, and PCB designs have been tested and refined. They are all posted here as of 8/9/2010 Updated video of the final system installed and working.

The build uses an Arduino, a Bluetooth plugin, and few chips to control the the process. The end result is a system where you can enter in a code on your phone that's transferred over Bluetooth then unlocks the door. It's not an easy build, but the guide walks you through each step pretty carefully.
