  • Put .h files in /include/
  • Put .c[pp] files to /src/
  • Add Arduino support libraries
• Get it to compile
  • Fix casing for <Arduino.h>, <SPI.h>
  • Make <avr/pgmspace.h> work with multiple platforms
  • Convert .ino to .cpp and add headers
  • Use main.cpp instead of main.c (mos build --clean)
