Summary of HX711 with a Four Wire Load Cell and Arduino | Step by Step Guide.

In this video, the presenter demonstrates how to create a simple scale using a four-wire Load Cell, the HX711 Amplifier module, and an Arduino. The tutorial focuses on a 20 kg Load Cell, contrasting it with a previous tutorial that used a three-wire Load Cell. The four-wire Load Cell features a full Wheatstone bridge, while the three-wire model only has a half-bridge configuration.

Step-by-Step Guide

  1. Wiring: The presenter explains how to connect the Load Cell to the HX711 module, emphasizing the importance of verifying wire connections.
  2. Arduino Setup: Instructions are provided for connecting the HX711 to the Arduino, including pin connections and downloading the necessary "HX711_ADC" library.
  3. Calibration: The calibration process is demonstrated, including how to save calibration values to EEPROM to avoid recalibration on every startup.
  4. Example Code: The video walks through loading example code to read from the Load Cell and how to adjust it for different pin configurations.

The presenter also mentions the possibility of integrating a display to create a fully functional scale, referencing a previous project involving a PCB and a 1.8-inch screen.
