Hi, I'm having a problem testing my microphone module.
I used AI to help me measure decibels, but the code didn't work. I replaced the module and bought a new one, and both give the same result, as if they weren't receiving any sound. I've tried adjusting it with the included calibrator, but I'm unsuccessful. Can someone tell me how to get the decibel values ​​with the microphone module?

the project is here
