Circuit Documentation

Summary

The circuit in question is designed to control two hobby motors using an Arduino UNO as the central processing unit and a motor driver to handle the power requirements of the motors. Additionally, two infrared (IR) sensors are included to provide input to the Arduino, which can be used for various sensing applications such as obstacle detection or line following.
