How to program for multiple tasks at the same time.

[Lab Student]

I want to start a data acq, then detect a level change in a switch which also corresponds to a visible timer starting. The timer will stop when one of three switches is closed. In the middle of this I would like for there to be a selectable (controllable/ adjustable) time delay andthen a signal is sent to one of three random lights. Can anyone please assist?

Ok, I took a shot at what I think you are trying to do. The attached VI monitors an analog signal. When the analog signal goes above 5V (could be easily modified for any level), the program pauses for a selectable amount of time, then writes to one of three randomly selected digital lines (the LEDs on my digital lines were reverse logic, so you might have to adjust the polarity). This will at least give you something to work with. Hope this helps!
