Hi guys. I've been watching the list for quite some time now, but haven't had too much input. I'm working on a car security system project for my car (because it was broken into yesturday and I'm pissed off). Does anyone have any ideas in mind? I'd like to use a 16F84, because I have them. I just need to know how I might go about it. I think I can use the door sensors that are already in the car (do they work on ground completion?), and I was thinking something along the lines of a rf keyfob for enable/disable. Then of course the blinking led etc. etc.. So, lets hear it, and ideas?
