  Turns LED_BUILTIN on and off repeatedly.

  LED_BUILTIN is defined as the correct LED pin independent of which board is used.

  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
  Serial.begin(9600);
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  Serial.println("HIGH");
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(400);                       // wait for a second

  Serial.println("LOW");
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(100);                       // wait for a second
