Microphone sound detection module

For sound detection Module has two outputs:

1. AO, analog output, real-time output voltage signal of the microphone
2. DO, when the sound intensity reaches a certain threshold, the output high and low signal

The threshold-sensitivity can be adjusted via potentiometer on the sensor

Connecting to the Arduino

• Pin + to Arduino 5+
• Pin - to Arduino -
• Pin A0 to Arduino A0 (for analog program)
• Pin D0 to Arduino 13 (for digital program)
