Doubts about op-amp based clap switch.....
I am working on a clap switch circuit which uses lm324 ic and i am amplifying my sound signal in three stages of amplifier now my doubt is which craterea should be satisfied so that on a desired intensity of sound i will get my output. can you show any ready made circuit if you have any??? But that should be tested because i need to implement it asmy mini project for engineering first year so please help me seriously...... thanks
