I would be interested to know the minimum complement of components
necessary
to support a single flip-flop.

Just one, the driver.

Is there a more specific term for "driver"? I am not familiar with a
component by that name.

I have a similar request as the original poster. I would like to use a
momentary switch to cycle among three LEDs. Is the circuit design for
this
using flip-flops complex?

If you have to ask... Simple for me might be impossible for you, but

Good point. Simple for me means that few (e.g., less than 5) components are
involved and testing can be done with a multimeter.

you haven't yet described what it is you expect the momentary switch
to do.

As I said, I would like to cycle among three LEDs. To elaborate: one LED is
turned on at any given time; each time I depress the momentary switch, I
would like the LED that is on to turn off, and the next LED in sequence to
turn on; the first LED is considered to follow the third in a cyclical
manner. I imagine that this circuit is functionally similar to one that
would drive marquis lights, except that instead of using a timer chip, it is
user-driven.

Is there an easier way to generate the same functionality?

What _functionality_?

I hope the more complete description above is easier to understand than the
one in my first posting.


It seems that there must be some ICs out there that provide
this kind of functionality out of the box. Does anyone know of any?

---
Pretty much any µC...

Is there one in particular that is best-suited to the functionality
described above?
