Hey,
I recently got given a free old door lock that uses an RFID "key fob" to open it. The friend that ditched it to me pointed out that it has a Mini-B USB on the bottom of it which led me to believe it's programmable.
Seeing as I enjoy destroying/improving things through destruction, I thought I'd ask you guys for help.
Currently, I've just plugged a Mini-B USB into the bottom and plugged that into my computers USB ports just to see what would happen. A second after it's in, a small orange LED flashes on and then off, a short beep is heard and the door locks. I assume this is a safety feature?
So all I know so far is that if you supply ~5v, the door will lock. Where can I go from here? It'd be cool to be able to unlock it via USB. I also thought that if I could work out what I need to feed it to unlock/lock it, I could just use the USB of my Android phone with some app that I can make to lock and unlock which would be really cool.
I assume what I need to do is read what happens on that USB port when I unlock/lock it with a key. Then I can just replicate it with my phone/computer using a program to send a certain pulse and then it should be under my control, correct?
(As a side question, my android phone has 'NFC technology', which I assume is just RFID? Is there any way I could program my phone to send the correct pulses to get the door to unlock with that instead of USB?)
I hope you guys can help. This looks quite fun and a nice learning curve I think.
