/* Arduino menu library example
Oct. 2016 Rui Azevedo (ruihfazevedo@gmail.com) www.r-site.net

Use the menu library with user code ctrl command

calling doNav with user command mode:

noCmd - clamp field values or do nothing
escCmd - exit
enterCmd - enter current option or validate field and exit
upCmd - move up or increment field value
downCmd - move down or decrement field value
leftCmd - move left or escape (not tested yet)
rightCmd - move right or enter (not tested yet)
idxCmd - enter option by index

this mode allows you to implement ANY input device

on this example only using
