Ignition-mod to control via arduino/tablet with lock code
I am new in here, and these requirements are part of my first ever car project or even any damn thing that I've done in life!
Basically, all I want for the moment is something to grant me access to my car's ignition only after I input a 4 digit code, either into my android tablet (that's already fitted as my in-car infotainment device) or an separate/standalone Arduino UNO.
-when I key-in, and turn the ignition lock to "ON", I want either the tablet or the arduino to ask me the 4 digit lock code
-when I punch in the correct code, the engine should start by itself or have access for an electronic push button start
I was thinking of hacking into my ignition harness and install in-between a relay switch which can be operated through the tablet or the arduino. Correct me anywhere you feel like. Because my idea is more of a fantasy, rather than practical use. But I guess, that's the purpose of this website, huh?
If I am able to execute this small wish properly, I want to go further by trying to control my power windows.
If this thing is already built or someone out there is tryin to accomplish the same stuff, please help me witha link or help me with your better-ideas and your valuable inputs.
Thanks a lot! Looking forward for all your replies.
P.S. - I have 2010 Chevrolet Spark with ZTE-V9 android tablet in perfect harmony with each other using Torque and ELM-327 Bluetooth OBD-II adapter.
