[dorkbotnyc-blabber] Looking for the right off-the shelf component

[Alison Lewis]

Hi all:

I've been asked to hack into a sensor that has four contacts (it acts
somewhat like a hand built joystick to control a moving image). Basically, I
am looking for a simple circuit that can do logic to know if any of the four
contacts are closed. If they are all open, then it should send out 2.5
Volts. I can program a PIC to do this, but I was hoping there was an off the
shelf solution out there somewhere. I was also thinking a timer could do the
trick, but I am open to other suggestions if you have any.

Thank You,
Alison
