stopwatch

[dragic010]

I need help with a very easy task. That task is: Stopwatch with Start/Stop button and measuring time of reaction between Start and Stop,and the best reaction time is shown? Thank you a lot with respect A.Dragic

Sounds like a simple homework assignment.  So what have you tried?  Where are you stuck?

I know how to make stopwatch,but i can't make it to restart elapsed time with using the case structure. Here it is picture how i tried. I need help with restarting elapsed time when pressing Start/Stop button,so i can measure reaction time between Start and Stop.

Is this what you're looking for?

It's similar like that only i need and stopwatch in that,when i press Start for stopwatch elapsed time goes off,when press stop for stopwatch elapsed time start counting,and next time when press start for stopwatch i need to restart elapsed time to starts from 0. I can't  find way to do that. Thanks for a solution.

Hi dragic,

read the help for ElapsedTime function and all it's inputs…

[crossrulz]

You don't need the case structure.  There is an input to the Elapsed Time to reset the time.  You will probably also need a shift register and a Select function in order to hold the previous time while you are stopped.

That would help,thanks a lot,now i need to measure time between elapsed time,and next elapsed time,and to show what time is less,i think i can figure out how to do that. Thanks again!
