"After you install one of these Bluetooth SPP apps, you can pair with your bluetooth modem connected to the Arduino. If it asks for a key, it will usually be by default "1234" (without quotes of course). After that, you should beable to send ABCD and the door strike will unlock for around 5 and 1/2 seconds, and then lock itself again."
The complete instructions and code samples can be found or you can see a demonstration of the locks in action below.
Watch the video below to learn more about the new Bluetooth door lock that is very close to raising the required $25,000 goal to go into production with still 23 days remaining on the campaign.
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!

Smart phone Bluetooth based door lock make it possible that you need not to take physical key or card any more. For easy use of the older and children, we keep the physical key.

“To open the lock, we will use the app LightBlue. It has a section called the Sandbox, that lets you control the LightBlue Bean without having to program your own iOS app. When the LightBlue Bean receives a serial message, it checks the bytes received against the keycode saved inside the sketch. If the keycode matches the buttons pressed in the sandbox, the Bean Lock will unlock or lock. Get the code from GitHub.
Also, remember to add a pincode to your Bean to prevent other people from reprogramming it.”
