Circuit Documentation

Summary

This circuit is designed to control two hobby gearmotors using an L298N DC motor driver, which is interfaced with an Arduino UNO microcontroller. The MPU-6050 sensor is included for motion tracking, and a 12V battery powers the system through a toggle switch. The Arduino UNO manages the motor driver inputs and communicates with the MPU-6050 via I2C.
