Sound Sensor Module  1     
Component Introduction 
Sound Sensor can detect the sound strength of the environment. The 
main component of the module is a simple microphone. To make sure 
the microphone can detect your voice properly, please try to change its 
sensitivity by turning the blue precise potentiometer on the module. Due 
to its preciseness, it takes at least 10 circles for you to get some changes.
