Turns an LED on whenever I receive a Facebook notification

void setup()
{
  // initialize the serial communication:
  Serial.begin(9600);
  // initialize the ledPin as an output:

  // check if data has been sent from the computer:

    led = Serial.read();
    // set the brightness of the LED:
    analogWrite(ledPin, led);
