HX711 with 4 equal resistors in a wheatstone bridge config

Hi, I was trying to debug a HX711 to see if it is functioning correctly. I wired 4 resistors in a wheatstone bridge config to the sensor, and was expecting readings of around 0 when printing on the uart terminal, but I get almost random values, ranging from -100 to 17000, back to 0 and -5000! Code: #include <HX711.h> HX711 scale; void setup() {} void loop() { int scaleReading = scale.get_value(100); Serial.println(scaleReading); } The bridge was hooked up like image on step 3 https://ww…

HX711 values from load cells

Hello everyone! I am a newbie in electronic and arduino stuffs but I am trying to build a scale to measure and register weight through the time. I used four 50kg 4 wired load cell (specifications in this link) each one connected to a HX711. Initially, one of the HX711 did not work using channel A (the measuring don't vary even I put different weights and I double checked the wires many times, I thought it would be the HX711 problem, but changing to channel B, I got reasonable values). I connect…
