Pressure Plate Stopwatch

Hi, me and my friend are doing a project with paintball guns. Pretty much we want to measure how long it takes for a paintball to go from point A to point B, wed be using a button to activate the stopwatch and once the paintball hits the pressure plate it stops the timer. Is this possible? If so can I have some sample code please? Thanks! :slight_smile:
