  • The WProgram.h file, which provides declarations for the Arduino API,
    has been renamed to Arduino.h. To create a library that will work in
    both Arduino 0022 and Arduino 1.0, you can use an #ifdef that checks
    for the ARDUINO constant, which was 22 and is now 100. For example:

#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#endif
