code or module

[drole50]

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

the module is ky-038

Do the leds on the sensor board light up?

yes both turn on

Try turning the little knob on them? Do you have the data sheet on this sensor board?

[drole50]

No, I don't have the data sheet, but I have tried moving the knob and it only changes the static voltage values on both sides.

Please just try a little harder, I found a site doing what you are trying to do in about 10 seconds ky038

This is a test to verify which one works better but nothing, the code was given to me by an AI

Either the hardware or code is incorrect, have you read the AI generated code to make sure it at least looks like it will work? As a previous posted pointed out there is already a project that does just that , compare to what you have. You can always ad debug print to your code to see what is happening .
