Code Documentation

Arduino UNO Code

void setup() {
  // Initialize digital pin D2 as an output.
  pinMode(2, OUTPUT);
}

void loop() {
  // Turn the LED on (HIGH is the voltage level)
  digitalWrite(2, HIGH);
  // Wait for 5 seconds
  delay(5000);
  // Turn the LED off by making the voltage LOW
  digitalWrite(2, LOW);
  // Wait for 5 seconds
  delay(5000);
}
