I am trying to do a project that I found on Instructables. I have all of the components for it, but when I verify, I get errors. I have looked up some problems and changed the time code to <TimeLib.h> as some have suggested for time related problems, but I'm still getting errors. Can someone look through it? It's a few years old, which is why some of the code needs to be updated, but I don't know what else needs to change. I've included the errors I get. There are many tabs of code, so I'm not sure how to post all of them on here. Please let me know if you can provide help.

// This ugly hack allows us to define C++ overloaded functions, when included

// intended to include "time.h" from the C library (on ARM, but AVR does not
// have that file at all). On Mac and Windows, the compiler will find this
// "Time.h" instead of the C library "time.h", so we may cause other weird
// and unpredictable effects by conflicting with the C library header "time.h",
// but at least this hack lets us define C++ functions as intended. Hopefully
// nothing too terrible will result from overriding the C library header?!
