-For this step, you can use the USB-to-serial chip to change the radio's settings, rather than reprogramming the radio through the Arduino. This is a good method for programming radios en masse.

-The next step was figuring out how to interface with a Zigbee using an Arduino. Fortunately, there are a couple of handy sketches here: https://learn.sparkfun.com/tutorials/xbee-shield-hookup-guide
+Next step was to hook up a Zigbee to an Arduino shield, and use the Arduino to send and receive messages via the Zigbee radio.
-One of these is a "chat" program, that just sends/receives messages. The other sends/receives data to read/write voltage values to pins on the board.
+Before doing this, we need to carefully check the settings of the Zigbee radio and make a note of the identifiers of the network and node for this Zigbee.

Repeater Program

	~~====Repeater Program====~~		See https://learn.sparkfun.com/tutorials/xbee-shield-hookup-guide

	The next program we want to do is to make a repeater program, with two connections open: one to the Zigbee radio transmitter, and the other to a serial port. If this program receives a message over the serial port, it will craft the correct hex commands to send that message out over the airwaves using the Zigbee. If it receives a message from the Zigbee, it will extract the message and display it to the serial console.		===Problems===

	~~See https://learn~~.~~sparkfun~~.~~com/tutorials/xbee~~-~~shield-hookup-guide~~		I connected the computer to the Zigbee, which was seated in the Zigbee shield, which was attached to the Arduino Leonardo board, which was connected to the computer via a micro USB cable.

			The first problem I experienced was due to the Arduino drawing a large amount of power. When the Arduino Leonardo was connected via USB to the computer (which was providing power), and the Arduino was running the beacon program (to transmit, then sleep), and the computer was on battery, the computer would randomly shut off completely and suddenly - and a "Message of Death" would appear saying the computer needed to reboot. The computer behaved okay once it rebooted, but it was worrisome.

			It was a sign the board was trying to draw more power than was available to it, and was sucking power away from the motherboard.

			The second problem was with the communication between the XCTU program and the Zigbee attached to the Arduino board. I had not carefully checked the settings of the Zigbee radio before mounting it onto the Arduino Leonardo, so before proceeding I decided to do that.

	To make this happen, we will upload a sketch to the Arduino that uses the serial protocol. The microcontroller on board the Arduino will open a serial connection with the Zigbee, and send characters through the serial connection to be transmitted.
