The other day I saw a product with a flashing LED, the flash rate was
set with a knob. Yes, a microcontroller with a pot connected to an
analogue input and LED hung off an output port. This is the sort of
thing I'd do with a couple of transistors or an NE555 depending on
which turned up in the junk box first.
$deity I hate modern electronics.
Surely a microcontroller is just a 555 with a few extra transistors?
Another tool in the box, just that it happens to be very cheap.
You should check out Usagi Electric on youtube:
https://www.youtube.com/c/Nakazoto/videos, he's putting together a
valve-based recreation of 1-bit processor (the MC14500B). He makes his
own PCBs too :-)
