My complaint is mostly driven by projects that claim to support learning but give not a single word about the electrical things happening, and only cover following the given software. Any computerized system needs to interface with the real world to be useful, even if that interface is a screen. And not mentioning that an output sources current to switch on a transistor is common to some of us, to others it is still some sort of magic function.Excellent points for me to consider. I respect your opinion and apologize for using nasty comments (they’re gone from my original post).
And I’m the person who mentioned fuses. As an example that using different terms is not an Arduino-only “problem”. From the point of view of a noob, I would find that confusing, too.
