My Own ESP32 IoT Device for Collecting Sensor Data - For Beginners and Arduino Users
My Own ESP32 IoT Device for Collecting Sensor Data - For Beginners and Arduino Users
I had been following others' ESP8266 projects, but I wanted to create a professional single PCB layout from a breadboard circuit just like they do. So, I was studying bits and pieces from foreign websites and YouTube. Right around that time, this course was uploaded to Inflearn, and since it perfectly matched my goals, I decided to take it. Before taking the class, I wanted to learn the following: 1. Basic setup for drawing schematics 2. How to design circuits 3. How to use KiCad 4. How to use BLE and WiFi on the ESP32 While points 1, 2, and 3 are available on YouTube, the information was often fragmented. I felt this course would help me build a solid foundation in a condensed manner. Regarding point 4, I wanted to learn it because I had failed in the past after blindly installing various libraries for BLE and WiFi without understanding the basics. The advantages I felt after taking the course are as follows: 1. It's in Korean. This is a huge advantage. 2. I gained the confidence to try making a PCB myself. 3. The flow of learning is natural as it connects everything from circuit design to firmware. 4. Using EEPROM to store/change WiFi SSIDs was a fresh idea I hadn't considered before. 5. It was not difficult to follow along. On the other hand, here are some points I found slightly lacking: 1. There was a part about connecting three diodes for ESD protection, but I was curious about why three were used and why they were only connected in one direction; however, there was no explanation for that. 2. This is a minor point, but the title bars of program windows or sub-windows were not visible, which felt a bit stifling at times. 3. I wish there was a highlight on the mouse cursor when clicking. I don't think there were any major drawbacks. However, I think someone with absolutely no foundation and only curiosity might need to watch it several times to fully grasp the content. In conclusion, I believe there is no other course as convenient and easy to follow as this one, provided you have the will. I look forward to follow-up lectures. Thank you.

While studying MCU, I was always curious about how to manufacture PCBs, so I decided to take this course. You explained everything in an easy-to-understand way, which made my studies very comfortable.

I didn't have any basics and only had a vague curiosity, but it was good to be able to learn the fundamentals and various other things. When right-clicking the mouse or selecting the top menu, it wasn't captured in the video recording... so I could only tell by listening to the sound. It was a bit difficult trying to follow along blindly without knowing. I downloaded the latest KiCad and it was version 10.0... So I re-downloaded version 9.0 to follow the lecture. They seemed a bit different... it was hard to follow without knowing the details.

I took this course because I wanted to study embedded systems again after a long time. Since the course follows a hands-on practice approach, it helped me a lot in getting back into the swing of things. I am looking forward to the next lecture, and it would be great if you could cover some more advanced topics. Thank you.

I looked into YouTube and books to try and make a custom board, but I felt lost because there wasn't as much information as I expected. The most helpful part of the course was the hands-on process of drawing the schematics and performing PCB routing myself using KiCad. Also, in Section 5, using the board I made along with the firmware source code allowed me to clearly grasp how data moves back and forth via BLE and Wi-Fi. Thank you so much.

I've been wanting to try making my own development board since using Arduino, and I was able to learn how through this lecture. The instructor explains everything in great detail.

I've completed about half of the lectures so far, and the process of creating a custom development board using a microcontroller is explained step-by-step from basic to advanced levels, which is very helpful for a novice engineering student like me. I think it will be a great help as I intend to create and use small modules combined with sensors in a wireless structure. I highly recommend this lecture, especially for beginners.
