Sound	Arduino	Description
VCC	5V	Power input
GND	GND	Ground
AOUT	A0	Analog data output
DOUT	D2	Digital data output

Examples

• Please download and install Arduino IDE to your PC.
  • Arduino Website
• Download the demo codes, unzip, and find the Arduino examples.
• Open the Sound_Sensor.ino file by the Arduino IDE.

• Build and upload the codes to the UNO board.
• After uploading, you can open the Serial Monitor of IDE and check the data.

Expected result

• The indicator lights up when the microphone of the module is near the source and goes off when it is far from the sound source.
• As the distance between the sensor and the sound source changes, the serial port output data changes accordingly.
