I am a student majoring in mechanical engineering. Since I was young, I have enjoyed making things move based on the code I wrote. Then, when I became a college student, I thought, "Ah! Arduino, STM, Raspberry Pi, Atmel, they are all good, but is there a board that has only the size and functions I want?" I started by googling and tinkering with various things, and I have also made a board, but I don't know much because my foundation is lacking. Then I met Coach Sam, and although it is an expensive amount for an undergraduate student, I think it is worth more than that. I would like to ask for more and better lectures. Thank you.
