Node-RED: IoT projects with ESP32, MQTT and Docker

Unlock the power of the Internet of Things (IoT) with Node-RED, MQTT, and ESP32! This online course is designed for Makers and DIY enthusiasts ready to elevate their projects.

Dive into a hands-on learning experience combining three powerful technologies to build sophisticated IoT solutions. You'll discover how to easily create complex projects using Node-RED, a visual programming environment that requires minimal coding experience.

MQTT, a lightweight messaging protocol, enables rapid and efficient data transmission between your devices, facilitating near real-time communication. The ESP32 microcontroller, with its integrated WiFi and Bluetooth, provides the processing power and connectivity needed for robust IoT applications.

What you'll master:

• Node-RED Fundamentals: Learn to visually design and deploy IoT workflows.
• MQTT Protocol: Understand and implement MQTT for seamless data exchange.
• ESP32 Integration: Develop and deploy projects using the powerful ESP32 microcontroller.
• Data Visualization: Collect data from sensors and visualize it in real-time using tools like InfluxDB and Grafana.
• Remote Monitoring & Control: Monitor and control your IoT projects from anywhere in the world via the internet.
• Custom Function Nodes: Create your own JavaScript function nodes to extend Node-RED's capabilities.
• ESP32 Programming: Explore state-of-the-art ESP32 programming techniques with C++.
• Dockerization: Learn to deploy microservices using Docker for simplified management.
• Database Integration: Set up and utilize Mosquitto MQTT Broker, Grafana, InfluxDB, and MariaDB with Adminer.
• PlatformIO: Implement ESP32 projects with PlatformIO.

This course empowers you to build your own IoT network, gather valuable data, and gain complete control over your projects. Whether you're a beginner or have some experience, the combination of Node-RED, MQTT, and ESP32 provides the flexibility and power to bring your IoT ideas to life.

After completing this course, you'll be equipped to confidently implement your own innovative IoT projects.
