Why is there all this complicated stuff? Is it really needed? I'm not criticizing, I just want to know for my own sake.

I did not write the code but I have read it and it does not seem to have any unnecessary parts. In my opinion it is written very cleanly and only contains the minimum amount of code needed to correctly use an ultrasonic range finder. You are right on target about what must be done to use a range finder, however I believe once you start coding it you will have a very similar solution. The only thing that I see that can be taken out of this code is some of the error checking but error checking is good practice since it means that you have thought of and prepared for things that can go wrong.
