VU Meter

Post by tusabez » Mon Nov 08, 2021 11:27 am

Hi all,

I would like to build a VU meter using a Pico along with a MAX4466 microphone and using an LED bar. I'm having a difficult time trying to get analog readings from the microphone through the ADC pin. So far nothing I've tried works. Any advice would be greatly appreciated.
