    Reverse in Experiment 7.3?

    If you are having issues trying to reverse in "Experiment 7.3 - Driving a “straight” distance", try modifying the comparison operator on line 85) by changing:

     while (rCount < targetCount)


     while (rCount > targetCount)

    The issue also might be relative to how the wires were connected to your motor driver.
