Thank you for your reply.

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.


---
The driver would be the device/circuit sending the information to the
flip-flop which would cause it to flip or flop.

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.

OK

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.


---
"Marquee" lights?^)
---

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.


---
Yes, it is.

I'll reply, tomorrow or the day after, with a schematic which will
solve your problem.

Thanks again for your reply.


You're welcome.
