Can you verify you are using the exact Arduino example for pin 9 that I included above?

The program you included before differed from the Arduino example so I am unable to help you further without knowing what complete code you are using.

To clarify, the loop() in the Arduino program loops over and over on the TinyDuino, so the first line of the code snippet you included " int brightness = 0; " initializes and sets the brightness variable to zero on every loop iteration. This is likely the problem. The brightness variable, as shown in the Arduino example I included, needs to be a global variable outside of the loop() function in order to be usable between loop iterations.

**CRASH!!*  (This is the sound of me banging my head on the desk).

DERP.

OMG.

I can't believe I did that.  Forty years of programming, and I made a rookie mistake like that.  Boy, do I feel dumb.  Thanks for enlightening me.  Now it works perfectly.

Here's my entire code:

Everything seems to be working... except that pin 6 & pin 9 seem to be on, both at the same brightness, and aren't fading or brightening.  Am I missing something here?

I actually "fixed" that problem -- however, the ramp up/down process was WAY too slow; I solved that by not only increasing the amount for the brightness, but calling the ramp functions before & after every delay within my 2nd function.  Not as good as I wanted, but good enough.

If you wanted the fade effect to move faster, you can decrease the delay. It looks like you have it at 50ms in your program.

I actually removed the delay, but it's still slow.  Ideally, I'd like all of my effects to be happening simultaneously, but that's just not possible.  I guess close is good enough.
