Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino Nano microcontroller, an MX1508 DC Motor Driver, two hobby motors, and two 4xAA battery holders. The Arduino Nano is used to control the motor driver, which in turn controls the speed and direction of the two motors. The battery holders supply power to the circuit.
