MQTT IoT Communication Project (Arduino, MQTT, Node.js, mongoDB, Android)

Thank you for the great lecture! There aren't many lectures that provide such comprehensive information. It's a shame that there's only one review for such a great lecture.

It will help you learn the basics of IoT using the MQTT protocol. However, it is not as up-to-date as before, so those who are not familiar with it may find it difficult. This is a lecture suitable for review purposes for those who already have some knowledge.

I was worried a lot because I was preparing my graduation thesis at university, but after listening to this lecture, I felt like I was gradually getting a clue about what to do. I am also grateful that you taught me server implementation and communication in an easy-to-understand way.

I took this course because I was interested in IoT and it was really helpful. Thank you.

I think it would be good for those who lack basic IoT knowledge or are just getting started.

I have experience using the WEMOS D1 MINI module, so this lecture was especially helpful and necessary for me. It was a lot of material, but I am so grateful that you conveyed the key content well in a short period of time. I had some difficulties during the theory and practice courses, but I learned more in the process of solving them. I am also grateful for the answers to my questions. ---------------------- The only regret I have is that there were times when I couldn't tell which part was being explained during the lecture. In other words, if you made the mouse location more clear, it would be much easier to watch on mobile devices. Thank you, Instructor Park Mae-il, for your hard work and thank you again for the great lecture.

It's good that you explained the details in detail.

thank you
