Thanks for your reply..COnsidering the fact that i want to build a clap switch.. wont the circuit i referenced be enough?I dont need to record the sound , just need to get the sound intensity. Is a comparator required? Ive read somewhere i can just connect a resistor in series with the mic.. and then take a capacitor from one pin of the mic and along with a capacitor connect it to an analog pin.. will that work?or should i just follow the circuit i referenced for the clap switch?Thanks..
