In this talk, we will cover some IoT basics, IoT Components, Web interface, and MQTT broker. We will show you how to install an MQTT broker (Mosquitto) on your computer. We will learn how to publish and subscribe to specific topics. You will learn how to install the Node-Red platform and add some useful extensions to it. Node-Red is a flow-based platform that allows you to quickly create web-based user interfaces to interact with your IoT system. Please have your ESP32 microcontroller and Laptop ready to follow along. You would also need to have the Arduino IDE installed along with the ESP32 libraries installed.
