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 of the Arduino UNO. The LED is connected to the Arduino through a resistor to limit the current and prevent damage to the LED. The ground of the LED is connected to the ground of the Arduino to complete the circuit.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Pins Used: GND, D10
• Purpose: Acts as the main controller for the circuit, providing a digital output to control the LED.

LED: Two Pin (red)

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

Resistor

• Description: A passive two-terminal electrical component that implements electrical resistance as a circuit element.
• Resistance: 220 Ohms
• Purpose: Limits the current flowing through the LED to prevent it from burning out.
