How do you make a load cell's amp HX711 measure both positive and negative values, or how do you set the center value for it? The main point is how to set the reference voltage (?) or something else so it can work like a joystick axis set it the center position, and work with an only lc or an extra one addadedadded, only one is preferable, say like a simple POT here.
That's a code for it.
#include <HX711.h>
#include <Joystick.h>
#define calibration_factor 400// Change this value to give accurate reading with your known mass.
#define DOUT 1
#define CLK 0
HX711 scale;
