// Arduino's pin connected to OUT pin of the sound sensor

1. define SENSOR_PIN 7

int lastState = HIGH; // the previous state from the input pin int currentState; // the current reading from the input pin

void setup() {

 Serial.begin(9600);
 pinMode(SENSOR_PIN, INPUT);

}

void loop() {

 currentState = digitalRead(SENSOR_PIN);
 if (currentState){
    Serial.println( currentState );
 else{
    Serial.print("Schii");
 }
