Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a red LED, and a 200 Ohm resistor. The Arduino UNO is programmed to blink the LED on and off at one-second intervals.

Component List

LED: Two Pin (red)

• Description: A red LED with two pins: anode and cathode.
• Purpose: To emit light when current flows through it.

Resistor

• Description: A resistor with two pins.
• Purpose: To limit the current flowing through the LED.
• Properties:
  • Resistance: 200 Ohms

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:
  pinMode(13, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

This code sets up pin 13 of the Arduino UNO as an output pin. In the main loop, it turns the LED on for one second and then off for one second, creating a blinking effect.
