    Mini Challenge 1: Forward to Stop Line

    In addition to signs and lights, self-driving cars also need to obey pavement markings, like this stop line telling where to stop.

    Modify your Color Sensor attachment, so that it faces downward,
    and program your robot to drive forward until it reaches the line.

    The program is very similar to the "ForwardRed" program.
