Hey Rob,
Since the old Technic 24t gear has full rotation off the differential,
And since the valve can be pushed back and forth by said technic gear,
And since the touch sensor is dead center of the valve stroke,
How did the program know which way the valve was going to be thrown by the
gear? I mean, how did the program know if the valve was going to be pulled
to the left or pushed to the right?
Or did you just set up the valve at the beginning the same way every time
and the program took it from there?
Just wondering.
