Hello all,
I have a car alarm that I want to use the output (say the horn) to
trigger a GPS locator so that if the alarm is triggered, it will
notify by e-mail that there is an alarm situation. The problem is,
arming and disarming produces an output. I need some sort of circuit
that will look for a pulse longer than the chirp (or double chirp)
that indiciates arming / disarming. Did I mention I'm an Uber newbie?
Someone mentioned this may be possible with an RC circuit. The output
it would require would be negative, though if someone has a circuit
that creates a positive output, I can get around this with a relay.
Your help is greatly appreciated.
