If you connect the light gate to a data logger it should do that for you.

Alright thanks a lot!
2 questions to clarify please...firstly,are both light gates connected to one data logger? (Or one light gate so the one that starts or stops?) Secondly,is the data logger then connected to a computer? I appreciate your help (and sorry for the long paragraph lol,my teacher never told us anything)

Hey, it's no trouble at all, don't worry. Us TSR members are here to help.
To answer your questions:

1) In my experience both light gates are connected to the data logger. It may well be possible to get wireless ones in the high-tech world we live in today, but I have not come across any.

2) The data logger is the computer here! There's no need to connect it to anything else, you should be able to analyse and collect the results from the data logger itself.

Hope this helps!

I understand that you have understood the concepts. It may be good to see how light gates are used in action. Below are two short videos that show different versions of light gates "in action".
