IoT networks are frequently complex environments where different devices have to communicate with each other. MQTT protocol is an enabler for standardizing this communication. See how to use it in this tutorial, regarding an IoT network based on Node-RED and Arduino. This link let's you download the Arduino code: https://drive.google.com/drive/folders/1CoaD6oqP--srGcMHWMSw4hI0NxT5slms?usp=share_link Chapters: 00:00 - MQTT Introduction 00:46 - System Configuration 10:28 - System Testing
