Xbee Outputting Values to Arduino

COMPLETE NEWBIE
You can ignore the commented portion if you're in a rush.
/*
*My current project is to make a robot arm mounted to moving chassis and controlled through a master slave *system, The chassis is complete and all that is left is the master slave system for the arm, and the building of *the arm.
*
*The slave of the system will consist of four potentiometers attached to a moving frame. The potentiometers *will be placed to allow for four degrees of rotation. The first potentiometer will be placed at the base of the *arm and will servo as a sort of a shoulder, allowing for horizontal rotation. Two other potentiometers will be *placed on the arm to serve as elbows and wrists, changing the vertical positioning of the arm. The last of the *potentiometers will be used to control the opening and closing of a claw on the front.

ACTUAL PROBLEM:
I am going to be using a pair of Xbees to read 4 analog potentiometers and transmit the values to an Arduino, where they will be used to control several servos.

My system will consist of an Xbee S2 on the master side and an Xbee S2 and Arduino Uno on the slave side. My four potentiometers (5v, 10k, rotary) will be wired to 4 of the 6 analog inputs on the master S2. This is when things get confusing. Because the recieving S2 cannot output analog values and only has 2 PWM output, I'm in a bit of a plight because I won't be able to read the values using an Arduino. The only solution I see to this is using the Rx and Tx pins to serially interface with the receiving S2. Here, I need to read the 4 potentiometer analog values uniquely.

To summarize my questions:

  1. Will reading the analog values through serial work? Are there any other methods of achieving the exchange?
  2. What is the basic framework for this method if it is feasible (i.e. what libraries should I use)?

Please question me further if you find this confusing in any way or require more information.

Help much appreciated.

Hi.
I see two possibilities.

  1. Add a second Arduino to the mix. Use this Master Arduino to read the analog values, and convert them to character values. Connect this Arduino to the Master XBee (Serial link), to send the character data.

On the receiving end, the "Slave" XBee receives the character values, and sends them (Serial link) to the Slave Arduino, where you can do with them as you wish.

  1. Or... feed PWM from the slave XBee into a Low pass filter, to convert to an analog value, and feed this to the Slave Arduino.
