Hello everyone, I am building a weighing machine using: 4 × 50kg 3-wire load cells HX711 amplifier module Arduino Uno :electric_plug: Wiring Setup: [image] HX711 → Arduino: VCC → 5V GND → GND DT (DOUT) → D4 SCK → D5 #include "HX711.h" #define DOUT 4 #define SCK 5 HX711 scale; void setu…

Disconnect one of the cells and check the wires, middle one(signal) should have 1000ohm when checked with other two, i had an issue where manufacturer mislabeled the colors and i wasn't using the correct middle wire for signal, the output was always the same. If the output changes when weight chang…
