[simpits-tech] Phidget question - analog inputs

[Brian Sikkema]

Alright, great. Thanks, Roy!

I'm gonna sit down tonight and try to get an estimate on the number of 
switches and lights I'm going to need, and get an idea of the phidgets I'll 
have to have. After that I plan on drinking heavily.

But it could be worse. I could be trying to build a fighter! :P hehehehe 
Hurray for 1950's technology!! ;)

The analogue phidgets I have use a 5v reference voltage output and a
corresponding input so yes, that would work with a 3-position switch and a
couple of resistors.
