Happy to help.  It might be easier to implement if the switch is
attached to an interrupt input pin (if you aren't using them for
quadrature decoding).

Sure.  I look forward to seeing it all together.

I've had some success with that too, but it's frustrating when you
come up empty.

As long as we have an option, I'm fine with it.  The exact
implementation is less important to me.

I remember seeing the LoS-Panel when that page was new (I happen to
have a few ATtiny2313 chips from my earliest purchase from Adafuit, of
an early-model persistence-of-vision LED blinker).  Around that time,
I started building a generic ATtiny2313 backpack board, but I don't
think I ever finished it.

Is your project using a newer chip, or will all of your code fit in
something that small?
