Last updated in June 2022 to support Node-Red version 2.2.2+ and Node.js 16.

More details about this update:In this update, we have added 10 new lectures that show you how to update Node-Red to version 2.2.2, and Node.js to version 16, as well as how to use several of the new nodes that come with Node-Red 2.

There's also a lecture showing you how to complete this project without having to setup an actual terrarium so that you can learn without the mess.

-------------------------------------

With this course, you will learn how to design and build an automated control system using Node-RED and the ESP32.

This course will guide you through the construction of an automated control system. The deliverable is a Terrarium controller.

Along the way, you will learn a great deal about useful technologies such as the Node Red programming environment and MQTT.

This course is perfect for Makers who are familiar with the ESP32 and are interested in learning how to use it alongside Node-RED.

Node-RED is a lightweight graphical programming tool. You can use it to join a variety of hardware and software components and create applications such as the automated terrarium controller in this course.

Node-RED is used in a range of settings. Makers to create home automation applications and organisations use it to automate their factory floors, among many other possibilities.

The ESP32 is a powerful low-cost microcontroller with build-in Wifi that we can program with the familiar Arduino IDE. Its "call to fame" is that it makes it easy for anyone that is familiar with the Arduino to leverage their knowledge and create gadgets that need more memory and processing power than what the Arduino Uno can provide, in addition to Wifi and Bluetooth. All this at a lower price point.
