Using a mic to activate an LED

Projects General Guidance
1

Hello!

I am new member to the world of Arduino, and am seeking some help with a project that I have in mind.
What I am hoping to do, is turn on an LED by clapping. I haven't started yet, but I'm thinking that I need a mic, maybe an amp (?).
I'm thinking that the clap would create an amplitude (?) which the arduiono can pick up. I'm thinking that I would make a program so that when the arduino picks up the signal from the clap, I would then activate the LED.

Hopefully this made sense to you all, and hopefully I can get some help with my project here!'

There are two sorts of "sound sensors" one will pass the sound waveform into the arduino and the other will pass the sound envelope into it. It is the latter one you want. It has what is called a peak detector on the end of the amplifier which just consists of a diode capacitor and resistor.
Make sure you pick the correct type. I am assuming that you are going to buy one rather than make one.
Good luck

Hi,
