This version of MicroMoth is tested with Arduino Mega 2560.
Make an Arduino project, and inside of the directory where {YourProject}.ino is stored, bring both MicroMothArduino.h and MicroMothArduinoMath.h to the same path.
And don't forget to add #include "MicroMothArduino.h" on your .ino file!
That's it! Enjoy.
