I want to make an wireless switch when pressed will give out sound from buzzer? Answered
I couldn't find any place where i could find them in my place and it's for science expo so it has to be DIY model.
My idea is that i attach the buzzer to car keys or something which is very small and gets lost every-time and when i press the wireless switch i will know where are the keys or my pen drive ...
so u must have got the idea..So folks please help me before 18 February 2011 24:00 Hours IST(Indian Standard Time)
