In this lecture, I provide a clear introduction to MQTT, a lightweight and efficient communication protocol widely adopted in IoT and mechatronic systems. The session explains how MQTT enables real-time data exchange between devices through the publish–subscribe model, allowing engineers to design responsive and scalable networks for sensors, actuators, and controllers. I also discuss how raw sensor data can be visualized and managed using dashboards and supporting IoT tools, helping learners connect theoretical concepts with practical implementation. Toward the end, I briefly introduce the REST API, another major web-based communication method, and compare its client–server structure with MQTT’s event-driven architecture. This video is ideal for students, researchers, and practitioners who want to understand modern IoT communication systems, explore data visualization, and learn how protocols like MQTT and REST API work together in connected smart devices.
