Avoid clash with Arduino defines (#3338) 

* Avoid clash with Arduino defines

* Arduino defines B0/B1 in "binary.h"
     #define B0 0
     #define B1 1
  This clashes with names of the template
  variables in conjuction

* Renaming them to "B" rather than "B1"
  Now it can be used as-is in Arduino projects

* Apply suggestions from code review
