MULITPLE INPUTS TO ARDUINO

Hello, I would like to use a potentiometer and a spdt switch with Max MSP. I have used Maxuino and SensorBox in the past but would like a simpler, cleaner approach (no opaque firmata code or 4051 chips).
I have used the "graph" code that come prepackaged with arduino software, but would like only one other input. Can somebody who is familiar with serial communication (I am not yet!) steer me in the right direction?
I am guessing using a for loop to scan through two inputs, and then lord knows lol.
Thanks a milli,
