"Dimming" : Shorter int call version
"Dimming2" :The long, original version
"Blink":simply blinking without fading
You can find the original Arduino code at Files>Examples>BasicsEdit the pinMode numbers to match the Sparkfun pinMode numbers you connected to.
The code for my specific solution is in a screen shot above.
