Hey Guys,

I am fairly new at this, so I am going to put some stuff out there and see if anyone can lead me in the right direction.

Right now I have a "quiz box" which interfaces with three sets of 5 seat pads. When all fifteen people are sitting in their seat, no lights are on, however, when a person jumps, his and only his light goes on...to identify the fastest jumper. It also has circuitry for resetting the lights and adding timers and so on.

Now for the good stuff...

I would like to write a computer program that will track the lights and also interface with a scoring program (which i haven't written yet, but will, once i decide how all this is going to work out.) My question is this:

Do I need to modify the circuitry and have a signal come off that into the computer, or could I let the computer do all the work...my idea(and let me know if this is not possible) was to use one pin for each seat(15) and let the newly designed computer program process everything, from determining who jumped up first to displaying the scoring dialogue.

I do not know what the pin assignments are...could they all be receiving data? And could they interface with a program?

I know this is alot. Can anyone who give some advice, or a place to start at least?

Thanks
