Robolab Photogate device and program

This is a plan and program for a Robolab controlled light-based photogate similar to those developed by Cambridge Physics Outlet (CPO). As an object of known size passes before the light sensor, the time of passage is recorded and can be used to calculate instantaneous velocity (v=d/t). Further modification may allow differential measurements between multiple lightgates and the calculation of average velocities to high precision. Ex. Time through light gate on port 1, time through light gate on port 2, time from leaving light gate on port 1 to time entering light gate on port 2, all yield valuable position, velocity, acceleration information.
