 VCC <-------> VCC
 GND <-------> GND
  S  <-------> Analog 0

==Examples==
 void setup()
 {
  Serial.begin(9600); // open serial port, set the baud rate to 9600 bps
 }
 void loop()
 {
      int val;
      val=analogRead(0);   //connect mic sensor to Analog 0
      Serial.println(val,DEC);//print the sound value to serial       
      delay(100);
 }
