基礎版:

#define __DEBUG__

#ifdef __DEBUG__
	#define DEBUG(...) Serial.println(__VA_ARGS__)
#else
	#define DEBUG(...)
#endif

進階版:

#ifdef __DEBUG__
	// You should only uncomment 1 version at a time!
	// Version 1
	//#define DEBUG(...) Serial.println(__VA_ARGS__)
	// Version 2
	#define DEBUG(...) Serial.println(__VA_ARGS__); \
					   Serial.print(" @ [SRC]:      "); \
					   Serial.println(__FILE__); \
					   Serial.print(" @ [LINE]:     "); \
					   Serial.println(__LINE__); \
					   Serial.print(" @ [FUNCTION]: "); \
					   Serial.println(__func__); 
#else
	// else DEBUG is diabled
	#define DEBUG(...)
#endif
