I have three strings of LEDs whose brightnesses are to

The dual inputs are for 'increase brightness' and
'decrease brightness,' so it's a simple 1/0 input.

Interval between sampling the inputs.  TMR0 would
do in a pinch.

Not critical, just above visual flicker rate and
with a 0-100% adjustable duty cycle.
