Interacting with ESP32 Using Node-RED and MQTT

The ESP32 is an affordable and powerful microchip that combines Wi-Fi and Bluetooth in one small package. It's commonly used in smart devices like home automation systems, wearables, and other IoT projects. Despite its low cost (around $6), it offers strong performance, and low power consumption, and is compatible with popular platforms like Arduino. Whether you're a hobbyist or a business, the ESP32 provides great value, making it easy to create wireless devices without a big investment. This tutorial demonstrates how to set up communication between the ESP32 and Node-RED using MQTT, along with an interactive dashboard via FlowFuse for a user-friendly interface.
