xbee setup
- download digi xctu software.
- connect via usb sparkfun board
- define a network number
- define destination radio serial number - printed on each xbee board
- lower broadcast strength
- tweak other settings
- repeat for second radio
Future Work
- Remotely control throttle
- Remotely shut down or start engine
- Integrate with GPS functionality
- Music arduino tones
