Another standout feature of Arduino's programming language is the many libraries you can import into your code. Libraries offer a range of extra functionalities beyond the base programming ...

(Hint: there’s no Arduino-provided code involved; hardware registers and the __asm keyword show up.) If you learned embedded programming in an earlier era, this will probably seem glaringly obvious.

So, Arduino started to look pretty good, everything already on a board. plugs right into the USB port. ... And so you’ll end up with code that is difficult to read when you see it the fist time.
