I have built a sms controller. It is really a great project and it works excellent.
I want to put it in my car, for when my car alarm goes off, the sms controller must sms me.
The problem that I have now is how to use the siren output to trigger the sms controller input.
I thought of using the siren output, but the problem is every time I activate or deactivate the alarm I receive a sms. I need a type of time delay circuit, so that if the siren go on for say about more then 5 seconds, the sms controller must be activated.
Hope you guys understand what I am trying to ask.
