arduino xbee temperature sensor - UPDATE

Been a long time since I looked at this project. Using Tom Igoe's Making Things Talk book, I got an Xbee with an attached potentiometer to send ADC data to an XBee attached to a PC.

Then the data was parsed in processing to plot a dual bar graph of sensor value (ADC) and signal strength.



The drioids.it XBee breakout board can be powered by up to 12V (on-board voltage regulator), and also has outputs for 3.3V.

To run a temp.sensor or other sensors will probably require a separate 5V circuit. The current circuit has the pot connected to AD0 (PIN 22) of the XBee, so could feasibily attach sensors to AD1,2,3 (all at 3.3 V).
