NRF24L01 example code with Arduino Uno and OpenCM

This could be solved by code like this
defining two macros

Thanks for improving the code, Should I just use millis function

@StefanL38

static unsigned long intervalStartTime; \
    if ( millis() - intervalStartTime >= timeInterval ){ \
      intervalStartTime = millis(); \

instead of the whole code if there is no any difference...
