I'm working on an LED thing for a music project. I want to be able to detect sound so that it can dim down after music stops and come back up when it starts again. The only thing is that the music will likely be very loud and "no music" will still likely be at least a bit noisy.
It doesn't need to be super accurate or quick, but it just needs to still be useful for detecting loud vs louder. I will be measuring with arduino, so it could be calibrated. But it still needs to not have an upper limit of just "fairly loud." Could this be done with a piezo buzzer?
Thanks
