Course Description

For Makers and DIY enthusiasts who want to take their Internet of Things (IoT) projects into their own hands.

Welcome to my online course on Node-RED, MQTT and ESP32! Designed specifically for Makers and DIY enthusiasts, this course gives you the opportunity to take your projects to the next level by combining Node-RED, MQTT and ESP32.

Node-RED is a visual programming environment that allows projects to be created easily and intuitively without the need for in-depth programming knowledge. MQTT is a lightweight protocol for data transmission in IoT networks, with which end devices can be connected quickly and easily. The great advantage of MQTT is that transmission is possible in near real time. The ESP32 is a powerful microcontroller that is ideal for IoT projects thanks to its integrated WiFi and Bluetooth support.

In this course you will learn how to use Node-RED to control and regulate your ESP32-based projects and exchange data via MQTT. You will learn how to build your own IoT network, collect data from sensors and visualise it in real time with actual programs like InfluxDB or Grafana. You will also learn how to monitor and control your projects via the internet and retrieve data from anywhere in the world.

This course is ideal for Makers and DIY enthusiasts who want to take control of their projects and deepen their knowledge of the Internet of Things with MQTT and Node-RED. The combination of Node-RED, MQTT and ESP32 gives you the flexibility and power you need to turn your projects into reality.

So let's get started and learn how you can create your own IoT projects!
