Camera software setup procedure summary (brief notes - read source code for details)
------------------------------------------------------------------------------------

- Program the AVR fuses for desired clock source [see notes in "./main.c"].
- Flash the bootloader, after compiling w/ proper clock choice [this step is optional, bootloader source code not included - you'll need your own].
- Flash the main program, after compiling w/ proper clock choice.
  - The included ./CC script shows example compile/link commands with flags set for an MPU6050 gyro sensor and external 16MHz crystal oscillator.
  - If you're using a different sensor, have a look at the source code to see what other flags are available.
- Install the board, plug in battery and servo, and turn on power. Hopefully the led illuminates and some messages appear on the serial port.
- Observe and verify reported fuse settings.
- Place the unit on a level surface and initialize the sensor calibration constants using the "I" command.
- Calibrate the battery using the "b" command, comparing indicated voltage to measurements made with an external meter.
- Setup the servo center position and left/right travel gains using the "r" command followed by the "+ -" keys.
  - You can turn off the automatic drift control off/on using "d" key to make this job easier.
- Save all settings, using "n" and "s" commands.
- Reboot using the "R" command and see if everything still works.
