Hi , I got an ina128p and a kitchen scale. I would like to weight stuff with it. The problem is I always get the same value from my analogRead. I tried with 2 different scales and eve tried to put the load cell back on the kitchen scale and it works. I think I am wiring the load cell wrong . I always get analog read value of 18 or 19. It changes constantly between them.
The way I did it :
Load Cell S- ---- Ina128 2 Load Cell S+ --- Ina128 3 Load Cell V+ ---- Arduino 5V Load Cell V- ------ Arduino GRN
Ina 1 --- 10k resistor --- Ina 8 Ina 7 ---- Arduino 5V Ina 6 ----Arduino analog0 Ina5 ---- Arduino GND Ina4 ---- Arduino GND
I wasn't able to find ina125 so I went on with ina128. I checked online for couple examples but according to ones I found I am wiring correct. Also the scale uses a 3.7V battery , so I tried to change the V+ to 3.7 but still it doesn't work.
I would appreciate any help
