You showed 176 lines of code and your errors start on line 180, so it's pretty hard to help you other than to say that your program seems to be longer than you think it is. And you repeated lots of things after line 180 that already happened before line 180.

I'm guessing you accidentally have two copies of the whole program in one file.

That's what I'm wondering. Why is void setup and void loop throwing an error.

Really need to pair this back to square one, I think.

TL;DR but either the above or you are including some header file twice. This may happen if you include a header which includes another header you have already included, and if the header files have no protection from multiple inclusion.

Well, given that they have the exact same post duplicated in "Programming" section, this seems plausible!  :-DD
