Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, an L298N DC motor driver, a Lipo Battery, two motors with reducers, and an MPU-6050 sensor. The circuit is designed to control the motors using the motor driver and read sensor data from the MPU-6050. The Arduino UNO serves as the central controller, interfacing with the motor driver and the sensor.
