help me troubleshoot my load cell sensors(4 pcs. bathroom type) my wiring is correct but the arduino wont read properly
I think you have the black wire where the white wire should go and you are reading the wrong ADC input
Please read this first

my wirings are correct
Then you need to tell us how you know the Arduino doesn't read right! What test equipment did you use to discover this?

Well then it is most obviously this:
The serial monitor is showing values that are fluctuating(positive and negative values) from the hx711. I checked the wiring i connected that i saw from
Also i copied the data from the channels github and im using arduino atmega 2560
Well, then it is most obviously the code.
Im using this type of hx711
HX711 delivers a fixed voltage on pins E+/E- to feed the Wheatstone bridge in the load cell and then it reads back the voltage on pins A+/A-. This is a very small voltage that is amplified and coded for digital output by the HX711. As @DaveX pointed out, there are some HX711 modules out there that are not properly grounded. Besides this, those small voltages are very susceptible to electrical noise (EMF).
Everything from the cables used (their AWG size, length, twisted or not, shielded or not, ...) to the solder points (your wirings are correct, so I understand everything is soldered), to grounding influences the final result.
If you sit back and read this whole thread, you will realize more information about your project is required for a successful troubleshooting.
