Remember the swing velocity is a (co)sine function. The highest speed is in
the zero crossing the tops are the left and right ends of the swing with a
speed zero.

not use the PIC to do time consuming floating point math. A
precalculated table makes
more sense here.

Yes, I am with you so far. My challenge is to actually

numbers.. :-)
Thanks, Bill.

Hi
Bill,
This problem is not hard to solve when writing new code for a clock, but
the constraint you have offered makes it hard to solve.
A faster loop would make it easy.
If it were my design, I would make the clock software use a main loop of
a few milliseconds (for example 200 loops per
microwave ovens!

Hi Chuck,
It appears you and I have different definitions of fun! :-)
I do still have the books btw, and I did look it up, found the
formulas, and
realized I don't know what to do with them

Regarding my previous mention of the LM3914, I was incorrect in stating
that you can only have a growing/shrinking stack of LEDs - there is a
Dot Mode that would provide the motion of a pendulum bob quite nicely, I
think.
