i stater relatively , trying manipulate sound sensor(this one: http://tinkersphere.com/sensors/919-microphone-sound-db-level-detector-arduino-compatible.html).
i used example code arduino(examples/01.basics/analogreadserial) , add serial.println. read value on output window , thought not right result. did response sound returned 1020~1023 maximum when quiet , 35~37 when yelled detector.
also tried calibration(https://www.arduino.cc/en/tutorial/calibration), still gave me either maximum or minimum. seemed not detect sound level if there sound.
i thought broken exchanged , got new one. still same unfortunately.
does have same problem , solve or know problem is?

some sound sensors have digital , analogue outputs (4-pin plug).
but 1 seems digital (3-pins).
so sound threshold detector (set blue pot).
not possible use sound level measurements without hacking.
this sensor should connected digital pin.
high = noise, low = no noise.
