Extremely urgent!! I need help figuring out how to connect an alarm to a PIR sensor! Answered
Skip to the second paragraph if you are short on time or get sick of me droning on.
Okay, so you've just done the first step in helping me, reading this. Me and my dad are sick of having our pumpkins trashed on Halloween just because someone doesn't like our football team. (there are other reasons too but that could take a whole book and a month to explain it) We live in a nice neighborhood where everybody knows everyone and things are pretty nice. However there are some people in our neighborhood who just don't give a freaking crap what their kids do, and I'm sick of it.
So I have a PIR sensor, Ladyada explaining how to use them, RadioShack, and Adafruit Industries. I also have an extremely loud alarm that goes off when the circuit is broken. I need some help figuring out how to make the PIR sensor break the circuit on the alarm. I have included a diagram explaining.
