Part 01 - Creating the code to connect to WiFi and MQTT.

In this super class, you will learn how to create a complete IoT project using ESP32, the MQTT Mosquitto broker and Node-RED. Let's start by connecting the ESP32 to the WiFi network and the Mosquitto MQTT broker, laying the foundation for MQTT communication. Next, we will build an interactive dashboard in Node-RED that will allow controlling a servomotor via MQTT, sending commands directly from the dashboard to the ESP32. Finally, we will implement a functionality where the servomotor will send back its current position to Node-RED, allowing the creation of a performance graph that will track the servo's movement in real time. This project will integrate various IoT technologies and concepts, providing a practical and applied understanding of these powerful tools.
Class Content
Part 1: Connecting ESP32 to WiFi and MQTT Broker
Introduction to ESP32 and its connectivity.
Configuration of the development environment (Arduino IDE and necessary libraries).
Code to connect the ESP32 to the WiFi network.
Configuration and code to connect the ESP32 to the MQTT Mosquitto broker.
