Trying to use RB-Onl-38 with strain gauge

Hi, I am trying to use the load cell amplifier RB-Onl-38 with a 120 ohm strain gauge. I have a Wheatstone bridge built on a breadboard with 3 120 ohm resistors and the 4th is the 120ohm strain gauge. I am using the code off of github, I am also using an arduino uno. I upload the code and run it but in the serial I am getting no change in values, I have tested my circuit and I believe it is correct. has anyone else had this issues? any advice would be a great help, I am very new to arduinos and have weak coding skills.

Thank you,
Ethan

Hi,

Can you post some clear pictures showing your circuit ? Did you make sure that you are reading the Strain channel that is actually used ? Did you try to vary the reference voltage potentiometer on the shield of the strain channel you are using ?
