Hi! I’m new to Arduino and I’m trying to measure the force of an object when grasping.
I’m currently trying to calibrate the strain gauge (120 Ohm) in Arduino, but the values are inconsistent and it continuously increases or decreases in value. I tried leaving the weight on for a good 5 minutes and the values still keep on increasing. Once I take the weight out, it doesn’t give the same reading as before and if I apply a smaller weight it can’t read it anymore.
Here’s the link to the library and code that I’m using
