GlobalBuildOptions.ino

/*
 * Showcase the use of embedded build options and global defines through a specially named .h file.
 * Sketch file name followed by ".globals.h", "GlobalBuildOptions.ino.globals.h"
 *
 * Example from https://arduino-esp8266.readthedocs.io/en/latest/faq/a06-global-build-options.html
 *
 * Note, we do not "#include" the special file "GlobalBuildOptions.ino.globals.h".
 * The prebuild script will make it available to all modules.
 *
 * To track the new sketch name when saving this sketch to a new location and
 * name, remember to update the global .h file name.
