lesserwords:
ok... I wanna make a clapper switch for my room that works with clapping no just any loud sound, so if you people out there can give me some designs or tips on how to make one plz and thank you.
Ps. Dontmake it too expensive  :P 

scrat:
By analyzing the sound wave of a clap you should find something which characterizes it against other sounds, and then try to recognize it by means of some filtering (if it's quite complex, also digitally inside an MCU).
There should be around many circuits to do this, usually electronic kit magazines offered them.
