Have you tested it and/or have a video of it working?
No, I do not have a video. No, I haven't tested it -- I post random code
because I like to mess with people's minds. Please re-read my post.
I'm curious about it. I could try it on pin 13 on mine but I don't think it
would do the program justice with that tiny baby LED.
Guess what? It won't work with the tiny baby LED on pin 13 because
pin 13 doesn't have PWM output. But, like I said, you could attach an
LED in series with a resistor from pin 10 to ground and try it out.
