√ Enter, save, and run Compiler directives.bs2 and check the program's behavior
against your predictions.
√ Change
#DEFINE LED_MODE = 1 to #DEFINE LED_MODE = 0.
√ Predict how the program will behave the next time it is downloaded to the
BASIC Stamp.
√ Run the program, and again test your predictions.
√ Repeat for the other four combinations of values that you can set
LED_MODE and
DEBUG_MODE equal to.
