Summary of the Circuit

This circuit is designed to interface an Arduino UNO with an InvenSense MPU6050 motion sensor and control a pair of motors using an L298N DC motor driver. The motors are powered by a 12V battery, and the Arduino UNO is used as the central processing unit to handle sensor data and motor control logic. The MPU6050 provides acceleration and gyroscope readings to the Arduino, which then processes this information to control the speed and direction of the motors through the L298N driver.

Documented Code

Arduino UNO Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a template for the Arduino UNO. The setup() function is intended to contain initialization code that runs once when the microcontroller is powered on or reset. The loop() function is designed to contain the main logic of the program, which will be executed repeatedly as long as the Arduino is powered.

The actual implementation of the code will depend on the specific requirements of the application, such as reading sensor data from the MPU6050 and controlling the motors via the L298N motor driver.
