Code Documentation

Arduino UNO Code

// C++ code
//
void setup()
{
  pinMode(13, OUTPUT);
}

void loop()
{
  digitalWrite(13, HIGH);
  delay(1000); // Wait for 1000 millisecond(s)
  digitalWrite(13, LOW);
  delay(1000); // Wait for 1000 millisecond(s)
}

This code sets up pin 13 of the Arduino UNO as an output. In the main loop, it turns the LED on for 1 second and then off for 1 second, creating a blinking effect.
