FWIW: I have owned a total of 3 different electronics kits as a kid. I
have no difficulty wiring together arrangements of switches, LEDs,
relays, and so forth. But all the manuals were a little vague on how
transistors actually work.
(I'm actually pretty damned certain I had some 7400s, and I made useful
circuits with them. But it was a long, long time ago now...)
Of course, when you buy a kit, somebody else has already figured out
what kind of LEDs to put in there, and what resister you need to connect
it to. I recall routinely using ICs to drive LEDs - but that was TTL,
and now I'm looking at CMOS, which has different characteristics.
Anyway, we'll see what happens I guess.
