Tutorial: Detect noise levels using a sound sensor

This sketch's purpose is to keep track of the noise levels in the surrounding area

Connections from the Arduino to the sound sensor:
• Arduino A0 pin → sound sensor A0 pin
• Arduino GND pin → sound sensor GND pin (- pin)
• Arduino 5V pin → sound sensor VCC pin (+ pin)
• Arduino pin 2 → sound sensor D0 pin

*/

//Define the variable soundSensorRead to Analog Input Pin A0
const int soundSensorRead = A0;

//Define the variable soundSensorPin to Digital Input Pin 2
const int soundSensorPin =2;

//Define variables
int sensorRead;
boolean sensorStatus;

//Commands inside void setup run once
voidsetup()
{
//Start the serial monitor at 9600 baud rate (9600 bits per second)
Serial.begin(9600);
//SoundSensorPin is defined as an input
pinMode(soundSensorPin,INPUT);

}


//Commands inside void loop run forever
void loop()
{
//Read the value of analog input from soundSensorRead and assign it in the variable sensorRead
sensorRead =analogRead(soundSensorRead);
//Read the value of digital input from soundSensorPin and assign it in the variable sensorStatus
sensorStatus =digitalRead(soundSensorPin);

//Check noise status
if(sensorStatus ==HIGH)
{
//Print to serial monitor
Serial.print("Alert, there is  high noise in the surroundings ");
Serial.print("| Sound sensor value:  ");
Serial.println(sensorRead);

}
else
{
//Print to serial monitor
Serial.print("Everything around you is peaceful ");
Serial.print("| Sound sensor value:  ");
Serial.println(sensorRead);

}

//Delay for 3 seconds
delay(3000);
}
