Hi!

We're a group of students at swedish digital media school Hyper Island who wants to achieve this:

Using Arduino to make LED's in a box light up when you scream into it...  :smiley-mr-green:

So, we only know the BASIC BASICS about how to use Arduino, and we would like your help to figure out:

What components do we need? (We have Arduino UNO Board Model)
What code do we need?
What else do we need to do?

...
PLEASE HELP!

Cheers.

You are going to need something that converts sound waves to digital or analog format. Typically, that is a microphone. Have you got one?

You need a microphone connected to an analogue input pin. "Electret" types are cheap and easy to hook up to an Arduino, all you need is a resistor and a capacitor.

Use the circuit on this page: https://en.wikipedia.org/wiki/Electret_microphone

I seem to remember seeing an Arduino-based graphic equaliser project which sounds like more or less what you're trying to achieve.

The output from the electret microphone will probably need to be amplified.

Did you mean "spectrum analyser"?


I think it was more like a VU display, which is probably closer to what DancingHomer is after.
