Hi, first post here, so be gentle. First off, let me explain my project.
I am developing a keyless system for my car, nothing to do with cental locking or anything fancy just for starting it. I plan to do this with a RFID kit, more specifically the MK179. I want to be able to get in, touch a rfid keyfob off a panel, then have a starter button that I push once to turn on the ignition, push (or hold) to start the engine, then push again to stop.
A bit of a faf, I know, but bear with me.
I have the RFID reader, keyfob and wiring it into my car sorted but my problem is with the starter button. I don't know to make it do a different thing everytime I push it. I can't figure out how to make it supply power to the igniton, then supply power to the starter motor then to kill it all again upon each push of the button.
This diagram may explain it better:
Now, I have a good grip on electronics, but analogue eletronics only and I imagine that the above will require a microcontroller or chip. So try and dumb all explations and adive down.
