I started with absolutely zero prior knowledge of electronic circuits or Arduino. Here are my thoughts after taking the course: 1. This is a condensed course that allows you to quickly build an MVP model with Arduino. I highly recommend it to those who want to create something with Arduino fast. 2. I once sent an email with an inquiry, and the instructor's feedback was both fast and detailed. 3. The lecture uses KiCAD 9.0, but downloading KiCAD now gives you version 10.0. This doesn't cause any major issues during development. 4. The overall audio quality of the videos is a bit low. 5. Even if you have zero prior knowledge of electronic circuits, it is perfectly fine to take the course while looking up unfamiliar concepts using GPT. 6. When accessing the Discord community URL via the "News" section, it says the invitation is invalid. 7. You can check the instructor's GitHub to see exactly what you will be learning before watching the lectures. Overall, this was a huge help. Thank you! Please make the next course soon!!

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.
