I have checked everything you mentioned, including the excitation voltage, signal voltage (A+ to A-), and confirmed the wiring according to the correct Wheatstone bridge configuration for 3-wire load cells. I'm also using the correct digital pins (not A4/A5), and the HX711 module is powered properly.
However, the issue still remains the same — I am getting either no change or very minimal fluctuation in the readings, even when I apply a known weight.
Any further suggestions or guidance would be really appreciated.
