Using relays to send input to computer
I have been wondering how it would be possible to monitor some of my car's functions via my pc. The main things I am thinking about are the doors opening and changing gears. I figure there has to be some way to notify my computer that this is happening because opening the door or changing gears causes lights to light up. I am somewhat new to electronics, but I am thinking that I could use a relay to control this. Maybe watching whatever line lights up the light...and using a keyboard controller to send notification to the computer. Would this work?
