// Arduino LED Blink Example

// The setup function runs once when you press reset or power the board.
void setup() {
  // Initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// The loop function runs repeatedly forever.
void loop() {
  digitalWrite(13, HIGH);  // Turn the LED on (HIGH is the voltage level)
  delay(1000);             // Wait for one second (1000 milliseconds)
  digitalWrite(13, LOW);   // Turn the LED off by making the voltage LOW
  delay(1000);             // Wait for one second
}

Explanation:

• setup(): Initializes digital pin 13 as an output.
• loop(): Alternates the LED state every second.

Upload the code to your Arduino board via the USB connection. If everything is set up correctly, the LED should blink on and off at one-second intervals.
