Distributed IoT System: ESP32 Hardware Control + C++ Backend + Flutter Mobile

Multi-layered IoT architecture integrating embedded systems, backend infrastructure, and mobile applications

Features • Architecture • Tech Stack • Team

📖 Overview

Projecto-Messio is a distributed IoT system developed for Programming 1 and Digital Design university courses. The project demonstrates real-world integration of hardware control, server-side processing, and mobile interfaces through a multi-component architecture.

ESP32 microcontrollers manage physical hardware (servo motors, LEDs, buzzers, sensors), a C++ backend handles data processing and business logic, while a Flutter mobile application with Dart backend layer provides real-time monitoring and control capabilities.
