X3 and X2 on my picture are used for centering voltage (constant data for Arduino). Then X1 and X4 are joystick pots (x & y direction). No more op-amp needed. | |

| Dec 22, 2021 at 13:23 | comment | added | Sieben | Oh, yes. My fault. The pcb is similar. Misunderstood the schematics. ) Like joystick x or y axis. It works but need a center here. | |
| Dec 22, 2021 at 13:19 | comment | added | Antonio51 | Is the pcb, one something as this sparkfun.com/products/13879. Anyway, you have access on all pins. Or do you want to use the load cell ... as joystick ? :-) | |
| Dec 22, 2021 at 13:17 | comment | added | Sieben | as far as i get it, we need a physical access for the load cells on a beam then. And how to make it with this sort of thing, is may be an another story. majju.pk/assets/uploads/2019/03/… | |
| Dec 22, 2021 at 12:54 | comment | added | Antonio51 | Ok. I did only use HX711 as a nanoVoltmeter :-) with "noise". Very good as microvoltmeter if one takes a mean of "some" samples. | |
