Thread: Blinking LED softly....
face BY : Dal Wheeler email (remove spam text)

I did something like this for a magic trick I helped a local guy with a
dinner theater develop.  The LED's were controlled by two nested loops.  The
inner loop controlled the duty cycle and the outerloop controlled the duty %
rate via a lookup table (the LED's I used had a percieved brightness rate
that wasen't exaclty linear; more logrithmic, so I plotted a curve in a
lookup table).  --A third loop could get the thing to blink; in my
application it was sufficient to bloom on and fade off.  Sorry, I don't have
the code handy, it was a few years ago, but you should be able to hack
something pretty quick.
