const int ledPin = 13;  // LED connected to digital pin 13
void setup() {
  pinMode(ledPin, OUTPUT); // Set LED pin as output
}
void loop() {
  digitalWrite(ledPin, HIGH); // Turn LED on
  delay(1000); // Wait for 1 second
  digitalWrite(ledPin, LOW); // Turn LED off
  delay(1000); // Wait for 1 second
}
```
