Circuit Documentation

Summary

This circuit is designed to control multiple DC motors using L298N motor drivers, which are interfaced with an Arduino 101 microcontroller. The Arduino 101 also connects to an HC-05 Bluetooth module for wireless communication. The entire system is powered by a 12V battery, which supplies power to the motor drivers and the Arduino 101. The motor drivers receive control signals from the Arduino to manage the direction and speed of the motors. The Bluetooth module allows for remote control capabilities via a Bluetooth-enabled device.
