Circuit Documentation

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 control the LED using one of the digital pins (D3) on the Arduino UNO. 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, D3
• Purpose: Acts as the control unit for the LED.

LED: Two Pin (red)

• Description: A basic red light-emitting diode.
• Pins: cathode, anode
• Purpose: Emits light when powered.

Resistor

• Description: A passive two-terminal electrical component that implements electrical resistance as a circuit element.
• Resistance: 200 Ohms
• Purpose: Limits the current flowing through the LED.

Wiring Details

Arduino UNO

• GND is connected to one pin of the Resistor.
