Rotary and Analog

This program monitors an analog signal and plots it versus the position read by a Vernier Rotary Motion Sensor. Among other things, it can be used to study diffraction by moving a light sensor connected to the Rotary Motion Sensor across the diffraction pattern. The data from the Rotary Motion Sensor is returned as position number, positive for clockwise and negative for counterclockwise. Printed on the Rotary Motion Sensor is the number of increments per rotation. Using that number and the sign of the returned data, you can calculate the net rotations of the wheel and the direction in which it was turned.

Two download options may exist:

Program - Download if you are running LabVIEW™ software and want to see the program and source code. Run the program, examine the code, make modifications, customize.

Stand-alone Application - These are software programs (developed with LabVIEW software) that work with the Vernier LabPro. They contain all of the features and functionality as described above. To run, all you need is the free LabVIEW 6.1 Run-Time Engine installed on your computer.
