This is a declaration, not a function call.
That crap makes the Arduino move the stepper, bypassing the stepper object, for 10 seconds.
Of course, the blocking nature will make the Arduino responsive as a brick for the same time,
screwing up the operation of ezbutton.
I call that function crap, because
- its name has no connection to its function
- it uses only global variables to control its operation
- the index of the for loop is signed, controlling a count
- significant delays are used
- the function is blocking
- the formatting is abysmal
