A note about flawed code examples.

I had two different microcontroller professors in college. Prof #1 gave me rather sophisticated routines with flaws written into them. My job as a student was to fix the bugs and get the code working. Prof #2 gave me a more simple objective and made me write all of the code from scratch. I learned far more from Prof #2 and his technique. I think that most of my fellow students would have agreed. A person needs to start at the ground level and work up, instead of starting off at the tenth floor in a total state of confusion.
