Hey everyone,
I'm a complete novice when it comes to electronics so hopefully this question isn't too insulting to anyone's intelligence. Essentially I'm trying to make a portable laser trip wire security system. Let's say I go camping for example. I'd like to be able to set up a few mirrors and my sensor and have a 360 degree perimeter around my campsite that will sound an alarm if anything crosses it.
I have everything working, but the alarm only sounds when the beam is broken; when whatever caused the disruption moves out of the beam, the alarm stops. What do I need to add to my circuit to make it so that the alarm stays on?
Bonus question: My alarm is very small and is powered by two AA batteries. If I wanted to use a louder alarm (I'm thinking a smoke detector), will swapping out AAs for a 9V damage anything? Again, I'm a total novice so I appreciate your patience.
-John
