Summary of the Circuit

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

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Pins Used: GND, D13.
• Purpose: Acts as the control unit for the LED, providing power and signal.

LED: Two Pin (red)

• Description: A basic red light-emitting diode.
• Pins Used: Anode, Cathode.
• Purpose: Emits light when powered.

Resistor

• Description: A passive two-terminal electrical component that implements electrical resistance as a circuit element.
• Properties: 200 Ohms resistance.
• Purpose: Limits the current flowing through the LED to prevent it from burning out.

Wiring Details

Arduino UNO

• GND: Connected to one pin of the resistor.
• D13: Connected to the anode of the LED.

LED: Two Pin (red)

• Anode: Connected to digital pin D13 on the Arduino UNO.
• Cathode: Connected to one pin of the resistor.

Documented Code

Arduino UNO Code (sketch.ino)

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

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

Description: This code configures pin 13 of the Arduino UNO as an output to control the LED. In the loop function, it turns the LED on and off every second, creating a blinking effect.
