Create v1.2

All version 1.x software has been tested to run on version 1.x hardware. Be sure you follow the appropriate instructions for the hardware, found here: http://makeitbreakitfixit.com/2014/02/09/sleeptrack-sleep-apnea-measuring-machine/

Any subsequent releases must have the first number in the software version match the first number in the hardware version. At time of writing there are no other hardware versions, but there very well may be in the future.
