Blinking Blues

Having some trouble with arduino blink. Will write up here. Draft now, not enough to really be of use to anyone but me.

Origin

I have been messing about with steppers and simple drivers for some time. Recently I put a logic analizer into use and noticed that the switching wave forms were a bit off. Simplifying this I went back to the basic blink and took a look at it. It also had some anomolies. This began an investigation of various blink code and the results. So far I have not found code that gives good results. In this investigation I am focusing on using pulses with half periods of 500 and 5000 micro ( not milli ) seconds.
