 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
void setup ()
{
 //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);
