I am having trouble coding a VI. I am wishing to make boolean based vi in which the user has to select a choice which color is brighter or dimmer? I want to randomize the choices so that it isn't always making a higher choice or alternate the presentation. I want to record the time of presses with the millisecond counter vi. I also want to record the number of correct and incorrect choices so that if they get 3 correct the colors seem closer in brightness and shift the color choices close to matching after 3 correct guesses until they get 3 incorrect guesses. Any insight on how to do this would help greatly.
