Human eye has a log response curve to brightness. So use micro to effect
log to linear behavior.

Correcting for non-linear brightness in LEDs when using PWM
When driving an LED with PWM, the brightness (as I perceive it) does not scale linearly with duty cycle. The brightness is slow to ramp up, then increases exponentially with duty cycle. Can anyone
