How can someone explain this to a kid? Is there somewhere an even more simplified version than Arduino or similar to show how all these things actually work? I know arduino is not a cpu, but overall, how these things work together, would be great to see/show.
I don't expect to show how electrons move :) I mean, some model, a toy or so, that shows how these things work. I remember it only from books/specs, but even there, at a certain point there are "limits" :)
