Electret microphone Sparkfun breakout by BARRAGAN http://barraganstudio.com

Reads values from a microphone connected to the analog input pin 0. The value read from the microphone is proportional to the level of sound in the near environment. The value read is printed to the serial monitor

int sensorValue;

void setup()
  Serial.begin(9600);  // sets the serial port to 9600

void loop()
  sensorValue = analogRead(0);       // read analog input pin 0
  Serial.println(sensorValue, DEC);  // prints the value read
  delay(100);                        // wait 100ms for next reading
