Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller board and a two-pin red LED. The Arduino UNO is programmed to blink the LED at a regular interval of one second. The LED is connected to one of the digital pins (D13) of the Arduino UNO, which is configured as an output. The other pin of the LED is connected to the ground (GND) of the Arduino UNO to complete the circuit.

Documented Code

Arduino UNO Blink Sketch

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

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

• Description: This code configures pin D13 as an output and toggles it between HIGH and LOW states with a one-second delay between each state change. This results in the LED connected to D13 blinking at a one-second interval.
