The sensor is an optional component, and there are various firmwares that use different types of sensors. If you are going to wave the device back and forth then a mercury or ball tilt sensor can be used. If you are going to spin the device in a circle then you could use a rotary encoder or a hall effect sensor or something else.

sorry, dude, no analog inputs on this baby, but maybe you can find an ldr that will hit the threshold for a logical zero at just the light intensity you want. maybe you can tune things a little with a voltage divider. alas, i'm pretty worthless on hardware questions.
