Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller and a red LED. The LED is connected to the Arduino UNO such that it blinks on and off with a delay of 1 second. The Arduino UNO controls the LED through its digital pin D13.

void setup() {
  // Initialize the digital pin as an output.
  pinMode(13, OUTPUT);
}

void loop() {
  // Turn the LED on (HIGH is the voltage level)
  digitalWrite(13, HIGH);
  // Wait for a second
  delay(1000);
  // Turn the LED off by making the voltage LOW
  digitalWrite(13, LOW);
  // Wait for a second
  delay(1000);
