DrDiettrich: I am making the sensors myself using velostat and wire and connecting them to the Arduino.
Blh64: Thanks - it seems like creating the sensors isn't too difficult (?) - just exposing two wires connected to the velostat that completes the circuit when pressure is applied. I guess I'll find out if that is a foolish assertion tonight or tomorrow.
INTP: I want to hook them all up to the same Arduino such that if any of them gets stepped on, the alarm sounds.
Thanks for the thoughts!
