const int ledPin = 2; // Use GPIO2 for the LED

// Setup function runs once at the start
void setup() {
  // Initialize the LED pin as an output
  pinMode(ledPin, OUTPUT);
}

// Loop function runs repeatedly
void loop() {
  digitalWrite(ledPin, HIGH);   // Turn the LED on
  delay(1000);                  // Wait for a second
  digitalWrite(ledPin, LOW);    // Turn the LED off
  delay(1000);                  // Wait for a second
}
