Circuit Documentation

Summary

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

Code Documentation

Arduino UNO Code

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
    digitalWrite(13, HIGH);
    delay(1000);
    digitalWrite(13, LOW);
    delay(1000);
}

Description: This code sets up pin 13 as an output and then enters a loop where it turns the LED on and off with a one-second delay between each state change.
