Serial or Speed..

This video above demonstrates the speed difference between serial enabled/disabled on an Arduino Uno while toggling a pin output. Just a really simple test of how fast it can pull a pin high and low (without using direct port manipulation), with and with out serial enabled. I think that was the smallest Arduino sketch I ever wrote..
