Show the measured distance value in the NXT display and add a description to the display. For example: “Distance = 30 centimeters” Also specify the measured distance belongs to which region or zone. You can determine range of zones due to your opinions. For example, range of zone 1 is between 3 cm to 25 cm and range of zone 3 is between 26 cm to 53 cm. But at least four zones must be specified. Powers of two motors in the NXT kit will be determined due to zones. In the furthest zone, robot will move in higher power and power will be decreased while getting closer to the wall. Play intermittent sound in the loudspeaker of the NXT kit. The frequency of sound must be determined due to zones. The program will stop after pressing the touch sensor or light sensor is on the black area.
You have a bunch of stuff to learn. Talk to your team-mates. Talk to your coaches. Talk to (and listen to) your instructors. Take it one step at a time.
Alternatively, find someone whom you can pay to do your work for you. I doubt that this is the correct forum to find such people -- however, there is a Forum for LabVIEW Developers Seeking Employment ...
From there it is pretty simple, continuously read the measured distance, convert it into a range, using that range set the motor speed and update a display. Are there any other issues?
