I may be wrong (I haven't installed the Arduino compiler on my new computer yet, so I can't try it today), but a variable defined in
setup() may not be visible in
loop() since those are two distinct functions. If you want a variable to be visible in both
setup() and
loop(), it must be declared
outside of the scope of either function, ie before the declaration of
setup() (after the
#define would be good).
