Awesome course, great use of microcontrollers to accomplish learning.

By Sai Ganesh Raju on 11/18/2025

The content was really good. But the presentation of the theory content could have been much better with proper slides. Information was so jumbled up that I had to constantly pause to grasp what is being shown. Otherwise everything else was great.

By Pablo Adames on 5/25/2025

Very detailed and useful projects. The teaching methodology is consistent and easy to follow. The resources are thorough and appropriate.

By Thomas Reidemeister on 5/11/2025

Well designed content. Very detailed. What is missing though is an update from the IBM cloud examples. IBM decided to retire the IoT cloud. If these examples could be updated with a locally hosted MQTT server this would be an awesome course.

By Avinash Gupta on 7/13/2023

The instructor has put a lots of love in making the course! That makes this course very informative and useful! Quality of the course and the material is high and well researched.

By Jim Wolfe on 4/25/2023

A very well organized course that appears to cover all the MQTT facets that one might encounter. Extensive use of Wireshark to examine data packet details really aids in understanding what's "going on under the hood".

By Parker Shute on 4/23/2023

This has increased my in depth MQTT knowledge dramatically. Well worth the time and money to complete.

By Anonymized User on 3/16/2023

Der Inhalt ist vollständig und ausreichen. Die Konzepte werden ausführlich erklärt. Die englische Aussprache ist manchmal schwer zu verstehen. Es wird zu schnell erklärt. Man braucht mehr Zeit die Diagramme zu verstehen.

By Paul D. Morton on 12/4/2020

Great job again from the Makerdemy Team. Thanks for sharing your wisdom with us at ISS!

By Adwaith on 11/19/2020

I have already enrolled in another MQTT course from MAKERDEMY. That was already a great course, but this course just took it to a whole new level. While implementing each project I was very involved and excited to see how each feature changes the nature of the packets. The packet analysis approach after each project is the most useful thing in this course. Take this course & you will truly become a Master of MQTT
