Error Compiling for Board Arduino Mega or Mega 2560 - Artificial Muscle Twister

I’m trying to build an open source Artificial Muscle Twister project (Artificial muscle twister), and for some reason, the code isn’t working. I downloaded the necessary libraries, ensured the uploading process was set, and did exactly as I was told and it isn’t working. I’m completely new to Arduino, so any and all help would be extremely appreciated.

The code is downloadable here: Artificial muscle twister.
