I have finally finished the course. Although I am not a professional in the field, I have studied this area deeply for a long time, so none of the concepts in the lecture were difficult to understand. However, even though I knew all the concepts, I found the parts involving the IDE and tool handling to be quite challenging. It was my first time actually working with a breadboard, and things like relays, OLEDs, FND controllers, and switches were incredibly helpful. At the beginning of the course, I even blew out an LED by connecting it incorrectly while just trying to light one up with a single resistor. But by the final project, I was able to follow the circuit diagrams and build the setup myself without much difficulty. Now, I can comfortably configure various settings like I2C and SPI right away. I especially liked how you would set things up first and then provide a general walkthrough of the code. Thank you.
