This embedded project measures distance using an ultrasonic sensor and displays the result on an LCD. When a valid distance is detected, the system controls a stepper motor to rotate in a clockwise ...

A pocket-size ultrasonic bladder-volume sensor has been constructed and tested with successful results. This paper describes the sensor and presents results from its use on healthy volunteers.
