Loop.
The loop() function execute continuously. the setup() is only executed once. In this example the onboard LED blinks forever every two seconds

    // The statements in the setup() function
    // execute once when the program begins
    void setup()
    {
      pinMode(48, OUTPUT);  // Set pin 48 (onboard LED) to OUTPUT
    }

    // The statements in loop() are run until the
    // board is stopped. Each statement is run in
    // sequence and after the last line is read, the first
    // line is run again.
    void loop()
    {
      digitalWrite(48, HIGH);
      delay(2000);
      digitalWrite(48, LOW);
      delay(2000);
    }
