Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a red LED, and a resistor. The LED is connected to the Arduino UNO through a resistor to limit the current. The Arduino UNO is programmed to blink the LED on and off at one-second intervals.

#define LED_PIN 2

void setup() {
  pinMode(LED_PIN, OUTPUT); // Set digital pin 13 (D13) as an output
}

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

This code sets up the Arduino UNO to blink the LED connected to pin D2. The LED turns on for one second and then turns off for one second, repeatedly.
