- Example using the SparkFun HX711 breakout board with a scale

-
- This example demonstrates basic scale output. See the calibration sketch to get the calibration_factor for your
- specific load cell setup.
-
- This example code uses bogde's excellent library: https://github.com/bogde/HX711
- bogde's library is released under a GNU GENERAL PUBLIC LICENSE
-
- The HX711 does one thing well: read load cells. The breakout board is compatible with any wheat-stone bridge
- based load cell which should allow a user to measure everything from a few grams to tens of tons.
  Arduino pin 2 -> HX711 CLK
  3 -> DAT
  5V -> VCC
  GND -> GND
-
- The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine.
