I'am not having any problems with my projects or so. I just finished it actually. And I just wanted to share it with the world.
I used 2 uno's. One with the gsm-shield to receive sms's from only my phone. And the other to control the central locking through a touch sensor.
Works as follows:
After receiving an sms with the right command, the arduino checks wether it can start the engine or not. (parking brake? neutral gear? engine already running? right sender number?)
If something is wrong, it sends back an sms with an error message.
If everything is ok, it activates my spare key already in the car, and starts the car.
Other way around if you want to remotely stop it.
The doors remain closed, until a well placed swipe on the windshield opens the central locking.
After the engine is shut down, another swipe closes the doors again and deactivates the key, ready for another start...https://www.youtube.com/watch?v=1w4JZll9xnI
