/*
* Nixie_Display_Backplane by Jonathan Zepp - @DaJMasta
* Version 3.3 - April 1, 2017
* For the Not Your Average Nixie Clock project
*
* Programmed to an arduino nano in the backplane, this software reads the required sensors and controls the driver boards. Includes
* an RTC, a temperature and humidity sensor, a barometric pressure sensor, a potentiometer to control brightness, and a capacitive
* touch sensor to change display modes easily. Reports actions and errors over a host serial connection and the display can be
* fully controlled through it. Translates String input to each tube and checks if they are capable of displaying the character needed.
*
* ver 3.3 changes:
* adjusted digit display count to not lose a digit when automatic rounding kicks in in the thousandths place
* adjusted tempOffset for accuracy (and converted to Celcius for easier math)
* added compensation for relative humidity read at a higher temperature (inside the clock) than displayed
* adjusted capsense reading window to accept smaller fingers more easily
*
* ver 3.2 changes:
* added serial command to set the RTC without having to reflash the chip and use a different sketch
* added automatic DST compensation and an on/off option stored in eeprom
*
* Built in Arduino iDE 1.6.5
* Uses:
* DHT library 0.1.13 http://playground.arduino.cc//Main/DHTLib
* DS3232RTC library 1.0 https://github.com/JChristensen/DS3232RTC
* SFE_BMP180 library 1.1.2 https://github.com/sparkfun/BMP180_Breakout_Arduino_Library/tree/V_1.1.2
* CapacitiveSensor 05 https://github.com/PaulStoffregen/CapacitiveSensor
