-  This is the calibration sketch. Use it to determine the calibration_factor that the main example uses. It 
also
-  outputs the zero_factor useful for projects that have a permanent mass on the scale in between power 
cycles.
-
-  Setup your scale and start the sketch WITHOUT a weight on the scale
-  Once readings are displayed place the weight on the scale
-  Press +/- or a/z to adjust the calibration_factor until the output readings match the known weight
-  Use this calibration_factor on the example sketch
-
-  This example assumes pounds (lbs). If you prefer kilograms, change the Serial.print(" lbs"); line to kg. 
The
-  calibration factor will be significantly different but it will be linearly related to lbs (1 lbs = 
0.453592 kg).
-
-  Your calibration factor may be very positive or very negative. It all depends on the setup of your scale 
system
-  and the direction the sensors deflect from zero state
-  This example code uses bogde's excellent library: https://github.com/bogde/HX711
-  bogde's library is released under a GNU GENERAL PUBLIC LICENSE
-  Arduino pin
-  2 -> HX711 CLK
-  3 -> DOUT
-  5V -> VCC
-  GND -> GND
-
-  Most any pin on the Arduino Uno will be compatible with DOUT/CLK.
-
-  The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine.
