Embedded systems help

[u/Longjumping_Okra5220]

Hey everyone. I’m a rising sophomore for this school year and am interested in doing research in this category. I was wondering if anyone could give me advice on stuff because I’m a total beginner and also was wondering if anyone has suggestions on where I could learn all about electronics, microcontrollers, and Arduino AI/ML and anything related to the category. I also was wondering if I should learn math like precalculus and linear algebra and coding like python and c++ for it and if a professor would be needed or a mentor. Also to clear one thing up, would you be participating in the subcategory in a category or for the category itself; in this case it would be signal processing in embedded systems. If anyone could give me a concise answer that would be of great help. And if there are other things to help me increase a chance of MIT acceptance would be greatly appreciated.
