Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, multiple resistors, and several two-pin red LEDs. The circuit is designed to connect each LED in series with a resistor to various digital pins on the Arduino UNO. The common cathodes of the LEDs are connected to the ground (GND) of the Arduino UNO. This setup is typically used for simple LED control applications where the microcontroller can turn LEDs on and off by setting the digital pins to high or low.

Wiring Details

Arduino UNO

• Digital pins D2 to D13 are each connected to a 200 Ohm resistor.

Resistor (200 Ohms)

• One end of each resistor is connected to a digital pin on the Arduino UNO (D2 to D13).
• The other end of each resistor is connected to the anode of a corresponding LED.

LED: Two Pin (red)

• The cathode of each LED is connected to the GND pin on the Arduino UNO.
• The anode of each LED is connected to a 200 Ohm resistor, which is then connected to a digital pin on the Arduino UNO (D2 to D13).
