The pingdar service is a basic system which allows simple range collection from an UltrasonicSensor and Servo. The UltrasonicSensor is swung back and forth and the range data is available to to consume by other services. The GUI shows a basic "radar" map of what is found.
TODO
Here looks to be an excellent implementation of this common use case in Processing :
