Hi,

First of all im not sure if im in the right topic.
With that being said,
does anyone know how i can make a 12vdc motor pulse on music using PWM with arduino?

Any help would be appreciated.

Have you hooked any audio input to the Arduino? Have you read anything from the pin you connected the input to?

If not, that would be the first step. Now, looking at the data that you get, what, exactly, do you want the PWM values to be for each value you read from the audio input source?
