Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with an L298N DC motor driver to control a DC motor. The Arduino Nano is responsible for generating control signals that are sent to the L298N driver, which in turn drives the DC motor based on these signals. The circuit is powered through the Arduino Nano, which also provides a 5V supply to the motor driver. Ground connections are shared across the components to complete the circuit.
