So basically we're doing an arduino mousetrap using a piezo to pull a peg from under a tupperware container, letting it fall on top of the mouse or whatever else we might catch. We're using a tilt sensor we made form a pen cap and a BB. The BB sits at the top of the pen cap, but when the mouse walks into the trap the BB falls down to the bottom of the tube, touches two wires, closes the circuit, which triggers the piezo, and finally pulls the lid shut. the weight of the arduino on top of the lid will snap it shut. We are also using a photocell sensor. A laser beam will be on the sensor at all times, but when the mouse walks in and breaks the beam, the circuit will close and the same events will occur.
