 Started with example code written by Nathan Seidle from SparkFun Electronics and added
 LCD output with gram and ounce values.
 
 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

 Arduino pin 6 -> HX711 CLK
 Arduino pin 5 -> HX711 DOUT
