This comprehensive course is designed so that students, engineers, developers, IoT enthusiasts... can learn Node RED from scratch to use it in a practical and professional way. Never mind if you have no experience in the topic and programming, you will be equally capable of understanding everything and you will finish the course with total mastery of the subject.

After several years working as an Engineer, I have realized that nowadays mastering Node-RED for the App Development is very necessary in IoT or other engineering applications. Node-RED is an open-source software that is one of the most powerful and versatile tools for low-code programming. Knowing how to use this tool can give you many job opportunities and many economic benefits, especially in the world of the development and IoT.

The big problem has always been the complexity to perfectly understand Node RED it requires, since its absolute mastery is not easy. In this course I try to facilitate this entire learning and improvement process, so that you will be able to carry out and understand your own projects in a short time, thanks to the step-by-step and detailed examples of every concept.

With almost 8 exclusive hours of video, this comprehensive course leaves no stone unturned! It includes both practical exercises and theoretical examples to master Node-RED. The course will teach you app development, deployment and integration in a practical way, from scratch, and step by step.

We will start with the installation of Node-RED on your computer, regardless of your operating system and computer.

Then, we'll cover a wide variety of topics, including:

Introduction to Node-RED and course dynamics
Download and Install Node-RED and configuring it
General familiarization with the user interface and elements
Flow Debugging, troubleshooting, switch and template nodes, msg object and use of API node
Data pre-processing, dropdowns, bat-charts, flow control and looping

In other words, what I want is to contribute my grain of sand and teach you all those things that I would have liked to know in my beginnings and that nobody explained to me. In this way, you can learn to build a wide variety of apps and flows quickly and make versatile and complete use of Node RED. And if that were not enough, you will get lifetime access to any class and I will be at your disposal to answer all the questions you want in the shortest possible time.

Learning Node-RED has never been easier. What are you waiting to join?

Who this course is for:

Beginners who have never used Node-RED before
Engineers, developers, students, IoT enthusiats... who want to learn a new way to develop Applications with low-code
