    Hey all,

    I want to build a toy of sorts that you could provide rapid movements esp in the Z axis, at a fairly high rate that would effect noises.

    I was thinking about an ultrasonic proximity sensor but they are pretty pricey. Would an optical sensor do the same thing? Can it be programmed to respond to a hand movement towards it as fast as a hand can move?

    Thanks!

    Human hand movement is pretty slow relatively speaking.
