This document provides a detailed overview of a circuit designed to control a drone using an Arduino UNO microcontroller. The drone is equipped with a Bluetooth module for communication, a GPS module for location tracking, a camera module for capturing images, and four DC Mini Metal Gear Motors for propulsion. The Arduino UNO is programmed to handle Bluetooth commands, read GPS and camera data, and control the motors accordingly.

This code initializes the Bluetooth, GPS, and Camera modules and sets up the motor control pins. It continuously checks for data from the Bluetooth module to control the motors and reads data from the GPS and Camera modules, printing the data to the serial monitor.
