So, if I number the HEs 0-7 like in the attached drawing and they are wired to PC0-PC7 for purposes of this discussion and the top of the drawing is North. Let's also assume that an activated HE has a value of "1", regardless of how we would accomplish that.
Then if the rotor is pointing North, what would be the value of "reading"? If the rotor was pointing South, what would it be?
