I see three occurrences:
Globally declared and initialized to zero
Set to zero in main to clear blink mode
Tested in TIMER2_OVF_vect to see if in blink mode
Can't figure out how it ever gets set non-zero to turn on blink mode???
Thanks,
Mike
How does timeunknown get set non-zero?

the online code is a little old, it may not be in there
