Simple Arduino LED Blink Cycle

This is a basic Arduino sketch that initializes the built-in LED and creates a continuous loop to blink it on and off every second.

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

// The loop function runs over and over again forever
void loop() {
      digitalWrite(LED_BUILTIN, HIGH);   // Turn the LED on (HIGH is the voltage level)
        delay(1000);                       // Wait for a second
          
            digitalWrite(LED_BUILTIN, LOW);    // Turn the LED off by making the voltage LOW
              delay(1000);                       // Wait for a second
}

}
}
