void setup() {
  // Initialize digital pin D12 as an output.
  pinMode(12, OUTPUT);
}

void loop() {
  // Turn the LED on (HIGH is the voltage level)
  digitalWrite(12, HIGH);
  // Wait for a second
  delay(1000);
  // Turn the LED off by making the voltage LOW
  digitalWrite(12, LOW);
  // Wait for a second
  delay(1000);
}

This code initializes digital pin D12 as an output in the setup() function. In the loop() function, it turns the LED on and off with a one-second delay between each state change, creating a blinking effect.
