+5V of sound sensor module to VCC(5V) of Arduino

OUT of sound sensor module to digital pin 3 of Arduino

GND to GND pin of Arduino

Source Code: Produce a sound close to the sound sensor, the LED will respond.

int Led = 13 ;// define LED Interface
int buttonpin = 3; // define OUT Sensor Interface
int val = 0;// define numeric variables val
 
void setup ()
{
  pinMode (Led, OUTPUT) ;// define LED as output interface
  pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor
}
 
void loop ()
{
  val = digitalRead(buttonpin);// digital interface will be assigned a value of pin 3 to read val
  if (val == HIGH) // When the sound detection module detects a signal, LED flashes
  {
    digitalWrite (Led, HIGH);
  }
  else
  {
    digitalWrite (Led, LOW);
  }
}
