// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin as an output.
  pinMode(14, OUTPUT); //14 = A0
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(14, HIGH);   // turn the on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(14, LOW);    // turn the off by making the voltage LOW
  delay(1000);                       // wait for a second
