What is new is that we indicate the pin for the backlighting
with
#define backlight
. This is a preprocessor command that will
replace all names occurring in the source code with the des-
ignation Backlight by the value 9. This way, you can perform
changes to parameters very quickly without having to search the
entire source code.
