TinyDuino Sparkler

[robrlstn]

Make the TinyShield 16 Edge LEDS sparkle. Through each loop a LED is chosen at random and its on-time delay also chosen at random. http://www.youtube.com/watch?v=rwu3iNypoQ0.

The code below is slightly modified code from the TinyDuino Darkness Guage by @tamberg (thank you).
