Taking Sound Volume and Doing Something With It

Community General Discussions

Hello

I want to take sound from my car speakers and use my 512 LED panel to display stuff when music is playing.

I'm guessing I will need a microphone connected to an analog input with my Arduino Uno?

I have been fairly successful programming the light matrix.

Thanks very much

What are you wanting to do with it?

If you could get line level inputs, you might be able to feed that directly, or, via some kind of level matching to an analog input. With analog in, you could get volume. If you added some filters, you could respond to different frequencies. My only concern to adding to a speaker’s connection would be the addition of impedance.

Have you looked at the MSGEQ7 IC ?

That IC will do most of the work for you by splitting audio into power levels for 7 different frequency bands, its widely used you will find lots of examples on your favorite video site.

I want to create a very simple device that reacts to sound using random visual displays (geometric and amorphic) using my 512 RGB LED panel - nothing really fancy or complicated, I hope.

I think I remember seeing things like this many years ago from RadioShack - the product was described “Lights dance to the music” or something really cheezy like that (ha).
