Circuit Documentation

Summary

This circuit is designed to control two DC motors using an Arduino UNO microcontroller and an L298N DC motor driver. It also includes a Bluetooth module (HC-05) for potential wireless communication. The motors are powered by a 12V battery, which also supplies power to the L298N motor driver. The Arduino UNO is interfaced with the motor driver and the Bluetooth module to control the motors and communicate with external devices.
