It seemed like an interesting idea at the time, I wanted to think up something that could be a cheaper alternative to a real car alarm.
Hence I had an old PIR motion detector lying around, and a simple buzzer.
The plan:
1 x motion detector
1 x noisy buzzer
1 x cable
1 x lever switch
Attatch the old burglar alarm to the power of the battery in the matrix board, looking at through the back of my van. Noisy buzzer attach to the normally open switch of my circuit. fix lever switch into the back door lock.
Open lock switches off disconnects circuit at lever switch, so the motion detector can blink away happily.
Conclusion?
Disaster!!! the Lever switch didn't work properly and the buzzer went off constantly, alot of headaches re-wiring with cables and no fix.
Never again!!!!
