1 9V battery
You can use three or four AA batteries
instead—if you have a battery holder for them. Anything
in the 5-12V range should work.

Xbee LilyPad
This will be the unit for the relay radio.
Alternatively, an XBee Explorer Regulated, or a Basic
XBee breadboard circuit, as described above, will work.
