Summary of the Circuit
This circuit consists of an Arduino UNO microcontroller, a red two-pin LED, and a resistor. The purpose of the circuit is to illuminate the LED using a digital output from the Arduino UNO. The LED is connected to the Arduino with a series resistor to limit the current and protect the LED from damage. The Arduino's digital pin 8 is configured as an output to control the LED. The ground pin of the Arduino is used to complete the circuit.

Documented Code
Arduino UNO Code (sketch.ino)
void setup() {
pinMode(8, OUTPUT); // Set digital pin 8 as an output
}
void loop() {
// Main code to run repeatedly:
digitalWrite(8, HIGH); // Turn on the LED connected to pin 8
}
File Name: sketch.ino
Description: This code configures pin 8 of the Arduino UNO as an output and then continuously sets it to HIGH, which turns on the connected LED. The loop function runs indefinitely, keeping the LED illuminated.
