need help with ad620an about load scale

hi i working on scale with half bridge and i got a problem with the code so if you can help me to know the code of my program i will be very thankful i tried alot of codes but i dont find the solution of that and i know that i connected the right wires and resistors and everything there right beacuse i found it works on friend working

i send to you guys the files that show my connections

i useing arduino uno and keypad 4x4 and lcd 16x2 that what the university want from me.

thanks :slight_smile:

I don't see a diagram and/or a picture of YOUR setup either.

A half-bridge has ONE 3-wire load cell and two fixed resistors.
I see four load cells on that picture.
So what DO you have.

Be prepaired to be disappointed with the resolution of an AD620/Arduino combination.
It will be ~200 A/D values at best.
A HX711 breakout board would be much better for this.

Thanks for your answer I bought the hx711 too how I need to connect him to the sensors and to arduino?

Enter "HX711" in the search box on top of this page.
There have been many projects with this breakout board.
Post a link to the sensors you have.
