Burglar Alarm!

Description:
In this lab, I decided to create a burglar alarm using an FSR, lights and the peizzo. I placed my wallet on the FSR and if someone tried to lift it, the alarm would go off with sound and lights. I decided to include lights as well to grab my attention in a noisy place.
Components:
1 Piezo
1 Arduino Uno Board
1 Bread board
1 FSR
Connecting wires
1 220 Ohm resistor
1 10K Ohm resistor
3 LEDs
Code:
 

/* Burglar Alarm

 * -----------

 *

 * Program to set off the burglar alarm when an object over the FSR is displaced or tried to be displaced

 * Modified by Priya Iyer on 10/15/2013 for creating a burglar alarm using an FSR
