#define Mic 0
#define LED 7
int val;
char state = 0; // state for Led if 1 LED is on
void setup()
{
  pinMode(LED, OUTPUT);
  Serial.begin(9600);
}
void loop()
{
  val = analogRead(Mic);
  if (val & gt; 65)
  {
    state = ~state;
    digitalWrite(LED, state);
    delay(1000);
  }
  Serial.print(“MIC value is: ”);
  Serial.println(val);
  delay(50);
}

This example shows how to use Microphone and catch sound
