Woo-hoo!  I got the last piece of code for the pet-feeder done
today (though I know there will be changes and added features).
Currently, it uses a 24-hr clock with 5 user-settable feedings
per day and variable feed quantities on each feeding.  Uses 3
buttons -- mode, up and down.  HW is 1 pic 16F872, 4 7-seg
digits, and  some glue (3 driver transistors, some resistors,
a crystal, etc).

I've setup a timing test where I'm running the code simultaneously
with a trusty stopwatch.  Is there some accuracy threshold that I
should be looking for?  By that, I mean what is considered poor
timing accuracy... how many seconds per day, or hopefully, per
month.

Also playing with the feed settings/alarms while that test is
running.

Next up .... the mechanicals, which is also being worked on by
a friend.

Thanks,
-Neil.
