Hey, the guy is using Arduino, well, you should use a resistance of 1 kohm, the schedule is the same as I show you, you must use the red wire inside and black outside your "penny" ... resistance to the ground will be used to enter the analog, as a ldr, is the same pattern ... You can check it on the web ... http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/ldr.html, also you would need a flex sensor... more stability and non erratic performance...
