Remote ESP32 Holographic Display System

This paper presents the design and implementation of a remote-update holographic display system utilizing the ESP32 microcontroller. The system facilitates dynamic image projection through a combination of hardware and software components. A web server acts as an intermediary for image storage and distribution, while a mobile application offers a user-friendly interface for image selection and system control. The ESP32, upon network connection and IP address acquisition, communicates with the web server to retrieve updated image data, enabling real-time content modification. This configuration allows for versatile and interactive holographic presentations. Key Words: ESP32, holographic display, remote update, web server, mobile application, IP address, dynamic projection
