IR Sweeper

   I got rid of the portions about the LED that were in the lab example. What remained was the function that read distance which I passed my increment and then made a simple test of the max value. The reason I can only sweep to 150 is because I kept running into problems when I would span the full 180 degrees. For some strange reason, the max distance would always set itself onto those outer 30 degrees. When I did limit my scope the problem solved itself. I am not exactly sure why this was happening. I think it might be the way the sweeper is pulling on the wires at that range. Either way, I have to call it after a certain time dumped into solving that problem. 

Statistical Models

   I am still baffled as to how to finish the the variance and standard deviation parts for the last two.

Cyptography

   I am still trying to find the way to do this. I have the feeling that it will require shifting my character array along the ascii table. I have some code and some pseudocode but I can not quite figure it out. First, I will sit between the lowercase parts.

 

   I can't really go onto the second part because I don't know how to do this whole casting section.
