This project presents an IoT-based wireless gun turret system designed for remote surveillance and control applications. The system is built using an Arduino Nano and ESP32-CAM module, where the Arduino Nano controls the turret movements and firing mechanism, while the ESP32-CAM provides wireless communication and live video streaming over the Internet. The complete turret structure is designed using 3D printing technology, making the system compact, lightweight, and efficient. Three servo motors are used for UP-DOWN movement, LEFT-RIGHT movement, and triggering the firing mechanism. Two DC motors are used to rotate the firing rollers for launching foam darts. The turret can be controlled wirelessly through a web page using a smartphone or any internet-enabled device from anywhere in the world. An ESP32-CAM module captures and streams live video to the user, allowing real-time monitoring and accurate control of the turret. A laser light is also controlled wirelessly for targeting purposes. The SR04 ultrasonic sensor is used for obstacle detection, while the DHT11 sensor measures temperature and humidity values, which are displayed on an LCD and uploaded to the web page through IoT. The ESP32 module continuously communicates with the Arduino Nano to execute control commands. The entire system is programmed using Embedded C language. This project demonstrates the integration of IoT, robotics, wireless communication, and embedded systems for smart remote surveillance and control applications.
