Calibration

[flyingwebie]

Hi there,

I really like your project. I would like to contribute and expand it. Especially, I would like to integrate it with ReactJS.
But at the moment I am facing some questions... for example the value that I tested with the test.js it's giving me the same value in a loop even if I try to put some weight on the sensor.
I have tested the sensor with Arduino and it works well! Could you help me to understand how I can calibrate it?

Thanks :D
