    hello friends,

    i'm in search of an audio senser/detecter..
    i dont need to cheak the intensity but just want to cheak if there's change in level of audio..

    i've seen a similar project..pics has been shown
    when you clap it rotates in one direction and on other clap rotation reverses..

    i want to know the name of the senser which is used in project..

    thank you friends... :)
