• Making an automated rig for chemistry test. Cannot read a load cell accurately.
  1 project | /r/ArduinoProjects | 30 Jun 2023

  I've confirmed the input and output resistances of my load cell are identical (995.3Ω) with an LCR meter. I've used Sparkfun's HX711 PCB because I heard the power supply on it is super noise-free. I've made the load cell rig out of aluminum and steel, so it's super stiff. Yet I still see constant drift. Values going down, down, down. Using basic example of the bogde library (link).

• Arduino Pro Micro - usb input lag with JoyStick library
  1 project | /r/arduino | 16 May 2023

  the lag is way more likely to be from the HX711, it is using a bitbang shift implementation with delays everywhere, have a read of https://github.com/bogde/HX711/blob/master/src/HX711.cpp if you doubt me

• Hx711 and uno not writing to array fast enough.
  1 project | /r/arduino | 17 Apr 2023

  My setup involves a load cell which with an HX711 using I2C to communicate over digital pins 3pwm for clock and 2 for data. I've been using the Hx711 library by bogde https://github.com/bogde/HX711

• Completely new to this, missing a step
  1 project | /r/esp8266 | 14 Jan 2023

  I have loaded the Wemos boards into the IDE through Boards Manager (using this guide), and the HX711 Library (linked in the project guide), though that shouldn't really affect testing from what I can tell.

• Weight sensor w/ nodemcu, HX711, load cells: Help! Can’t calibrate.

  I'd try using the HX711 lib that Tasmota is using directly in a test program. If that works then you know it's an issue with the Tasmota code specifically.
