| #64: How to measure speed with a counter/timer This video shows how to measure the speed of an object using a Frequency Counter/Timer. The counter/timer is used to measure the time difference between two sensors that are triggered by the moving object, then simple math is used to invert the time measurement. If the distance between the sensors is fixed (one foot for example), then the inversion will show the velocity (in ft/sec for example). https://youtu.be/ytJEsdmQXW4 |
