Hello,,i am using arduino with xbee antennas for three analog pressure sensor inputs. I got some values for a particular condition. with the same condition,while connecting arduino alone to the laptop (with Xbee) the values are slightly lesser than the previous. Can anyone help to find the problem, urgent please..
The Xbee transmission can affect the Vcc and default AREF for the analog inputs. Using the 3.3V output for the reference voltage may give more stable readings.
