CAR ALARM

[vvvv]

Lately my car has been interfferd with. ergo towed into the middle of the road and left there causing obstruction and danger to traffic.

So out came the angle grinder to take of the tow hooks.
Then I decided to design and install a movement (schock alarm)

Used a PIC12F625 and a tiltswitch.After 15 hours design and development I gave up.It works.Switched onwith a keyswitch on dashboard.Waits 8 seconds to aram to give me time to get out of car, and then sounds alarm on schock i.e. movement to car. I had also programmed it to auto switch off alarm after 5 minutes,sometimes it does sometimes it doesn't.Used both GPIO1 a(interrupt on change) and GP2 external interrpt.

Anyways thats it .spending no more time on it.as it works fine as alarm.
Looking on tinternet Sparkrite SRA2 schock sensor alarm for 30 quid.
Don't know why I bother since this unit also has 2 fobs and the sonder has more db's than mine!
