Single-shot may not be the right name, and it may not be a 555, but I’m imagining a circuit that outputs a short discrete pulse upon transition of an input from high to low (or vice versa), and does not re-trigger until the same transition occurs again.
Since I am imagining someone else doing it, it seems like a very easy job.
Of course it could be done simply with a microcontroller, but I was wondering if there's a discrete solution that would avoid needing a 5V supply. On the other hand if you need a DC supply at all it may be just as easy to use a microcontroller.
