Hey, FT folks. I would like to build a device that uses photoelectric sensors to time a car rolling down a track for my physical science class. Here are the requirements:
1. Photoelectric sensor starts timer when the car passes the sensor.
2. Four additional photoelectric sensors spaced along the track will identify the time it takes the car to reach each sensor.
3. A controller recording the time to each sensor. The times can either be displayed on a digital or LED screen or downloaded to a computer application, such as Excel.
I've done this activity with students manually timing with stopwatches, but they pretty much suck at that. Can anyone help me out and give advice on how to do this?
Thanks!
