Using mic to light up diode -> newbie

[Cool.Majkl]

Hi!

I got a project at school to finish, and I thought, that I could make it on my RasPi. But the problem is, that I'm absolute newbie in programming. I need to connect mic and diode to RasPi, and light it up with claping.

Any ideas where I should start?

well, the easiest way is to just use a mic element and comparator to tell when a loud sound, like a clap is detected and it'd send a pulse out, and into a pin on the raspberry pi, just make sure you use a voltage divider so it doesnt go over 3.3v, but have a python program detect it using input(), and use that trigger to turn on/off an LED.

here's an example circuit that Ive used in a few projects, it was taken from a robot that detects a tap on it, or clap, or loud noise to activate.

another alternative is hooking up a usb sound card and using pyaudio to detect the audio, and turn on the LED pin, but the only thing about that is the sensitivity of it.
