    Custom Arduino keyless entry + auto window/trunk integration...

    Did a first test of my custom Arduino keyless entry system and well, it works!



    I'm using the following:

    Arduino micro controller
    4channel wireless stamp(ebay special)
    ULN2004 transistor array

    The hardware is pretty simple. The software was a bit tricky. I have it setup to do 4 functions for each button. Click, double click, hold, long hold. So I have a TON of things I can do. Right now it's just the normal functions + trunk and I integrated it into my auto window controller(also arduino based).

    Added bluetooth support to be able to control it with my Android based phone.

    Using a RN-41 class 1 bluetooth module. See a few posts down for the app interface.

    Thanks guys, I love tinkering around with electronics. Every new project I learn a lot and it's fun.

    Right now it's still on a breadboard for testing. Once I get it onto a board it won't be very big. Maybe 3x2x1 (guestimate). I can get away with it because I'm not using any relays that you'll typically find on security systems/keyless entry because I know that everything I already tap into are relays so I'm not working with high current. I don't plan to make anymore because this is just a custom thing I was interested in doing. My goal is to end up with bluetooth support for my android phone. I don't mind helping anyone else out if they are interested.

    I really wanted to do a true proximity, so when you get 10ft or so from the car, it automatically unlocked. RFID looked best but the passive ones don't have the range I was looking for. Bluetooth was a possibility but power was a concern, so I was looking at miniRFs.
