Hello, all. I am currently trying to program a black pill board to print out the output from a sound sensor, for which I use the Arduino IDE 2.3.2. Used components:- STM32F411CEU6 black pill- KY-037 sound sensorCurrent connections:- the "G" pin from ...

I double-checked the contact on the black pill pins and it seems that it fixed the issue. Apparently the contacts on all the pins were a bit weak, so I reinforced them a bit and now I am getting an actual output. Now I get values around 690 in silenc...

What do you mean "high or low"? The sensor has both an analog output pin and a digital one. If I use digitalRead, I just get a constant output of "0", even when I can clearly see that L2 is on.

I already am. Is A9 not analog?

Quick correction for the last point in other relevant info. The values don't change if "A9" is connected to the "D0" pin on the sensor instead of "A0".
