I'm making a blue-tooth keyed push button start for my car, it uses your phone as the key, uses simple encryption with the signal. Wont allow you to start the car without the phone present,
My main concern is that I dont want my car to have any possibility to ground out and shutoff while in motion. If there is a malfunction with the Arduino or something.
Could I use an SCR to "latch" the ignition wires up to 12 volts constant, then it can only unlatch with the signal from the Arduino when you press the button again, but if the Arduino fails it would still not turn the car off while in motion?
I just dont want my car to shut off going down the highway 70MPH haha any ideas to improve the design?
Its an Auto transmission so no worries about the increased safety issues with manuals
