motion activated alarm, sort of Answered
my wife just bought a tin pig that is about two feet tall and she wants me to see if i can make it squeal when someone walks up to our front door. i figure it sounds like an easy project but i am not sure. i have enough experience wiring, soldering, and general tech stuff. i have read up and can guess that i will need a pair sensor and some sort of micro controller, but i am unclear what or what to do with it. the goal is to have a piece that i can put inside the pig and have it detect a visitor and then trigger a sample of a pig sound. i know its silly, but i do what the wife asks!!
ideas of maybe a link to something specific would be helpful!
