Circuit Documentation

Summary

This document provides a detailed overview of a circuit that primarily consists of an Arduino Nano microcontroller, a TB6612FNG Motor Driver, two DC Motors, and a 9V Battery. The circuit is designed to control the two DC Motors using the motor driver, which is interfaced with the Arduino Nano. The Arduino Nano is responsible for providing control signals to the motor driver, which in turn drives the motors. The 9V Battery supplies power to the system.
