Introduction

Analog Sound Sensor is typically used in detecting the loudness in ambient environment. You can use it to make some interesting interactive works such as a voice operated switch

Specification

Supply Voltage: 3.3V to 5V

Detecting sound intensity

Interface: Analog

Sample code:

void setup()

{

Serial.begin(9600); // open serial port, set the baud rate at 9600 bps

}

void loop()

{

int val;

val=analogRead(0); //connect mic sensor to Analog 0

Serial.println(val,DEC);// print the sound value to serial monitor

delay(100);

}
