    I need to make a Zumo that roams a track ( the track is tape on a table, black tape ) and uses an ultra sonic component to detect where to go and stay with in the bounds.

    It would be best if i could only use 1 sensor.

    Can any one offer any help/resources such as code, example systems, etc?

    Welcome to AAC!
    If the Zumo is constrained to follow the tape, won't that keep it within bounds? I'm puzzled as to why you'd want an ultrasonic sensor in addition.

    The ultrasonic sensor is used to identify the competitor or an obstacle. It is not used to follow black/white line on a board.
    Use the reflectance sensors for that. Infrared light (IR) is absorbed by black and reflected by white so you can easily tell whether or not you are on/off the line as you monitor the sensors.
    It should be included in your kit.
