Additionally I'd like to use some of the analog inputs on the arduino to monitor status (of items controlled by my digital outputs) and have the xbee on my fio sending back the info.
You want to connect digital outputs from the XBee to analog pins on the Arduino. Why? Something is not quite right in this statement.
Essentially what I have is a small mp3 player, LED strobe , and a gopro camera that I'd like to control. each has a separate operating voltage so the Digital outs actually control relays that will apply the power when the digital outs are driven high. The analog Inputs will actually be connected the mp3 player / strobe / camera to make sure the power distribution is working well.
sorry for the confusion
