Arduino to Xbee

Solder the Xbee breakout boards. I recommend soldering the straight headers in first and then the 2mm sockets.




Connect the 9V positive lead to the base of the 9 to 5 volt voltage regulator (I use a 7805). Connect the battery negative lead to ground. The 7805 ground to the ground and then the 5 volts out to the power strip. Connect the Arduino to ground and power. Connect the accelerometer as mentioned in the previous post. Connect the power to the 5 to 3.3 volt voltage regulator (3940IT). Connect its ground and power out. Important note that the 5 volts in and the 3.3 volts out are reversed in the 3940. Use a multimeter to test if you are not sure. Putting 5 volts into the XBee has a good chance of frying it. Using the XBee Sparkfun breakout board connect VDD (power to the 3.3V power) Connect ground to ground. Connect DOUT to the Arduino's RX and the DIN to the Arduino's TX. Connect an LED to the ON pin to test for power. This LED does not need a resistor as it is operating at 3.3 Volts.
