Hi everyone, I'm new here, and new to arduino. I don't have much experience with electronics but I've got some experience coding. Last year I got and installed a new alarm on my car. It's a Viper 5701. I've checked and it's SmartStart compatible which means I can add a module so I can Open/Close and other stuff from my cell phone. I checked their app and there aren't enough options to justify the price tag they're asking for the SmartStart module.
My question is it possible ( and how hard would it be ) to create a software on my arduino that can talk to the alarm on my car? The module has 4wires for communication + 2 for power as you can see in this picture:
Without any information about the bus and protocol used by the module and alarm I believe it would be really hard. I intended to add a GSM and GPS module to arduino to track my car and perform lots of tasks from my android. Any feedback appreciated.
