A common question concerning our Wheatstone bridge amplifier shield is “How can we stack two together with three or four load cells?”
This is actually quite simple and only requires a few components…

hey, can we use four button load cells with the two loadcell amplifier shield, to measure the weight.

@NIkhil komalan: Short answer: Maybe, but it is very likely.
Long answer: This depends on what kind of button load cells you are using. If it has 4 (or 5, two grounds) wires (ex: RB-Phi-121), then it is most likely a full Wheatstone bridge and you can use it with the two Wheatstone bridge shields without issue. If it has only 3 wires then it is a partial Wheatstone bridge and you will need to add other components before you connect it to the RB-Onl-38. You can find more about it with an online search about “3 wire load cell”.

HI Sebastien,

I have four 4 wired load shields RB-Phi-118. And two Wheatstone shields RB–Onl-38. One Arduino Uno. In you article I will connect two load shields to (Strain1 and Strain2 connectors) of the first Wheatstone shield. Then place second Wheatstone shield on the top. I will bend A0 and A1 pins of the first Wheatstone shield and connect them to A2, A3 of the second Wheatstone shield. Then connect third and fourth load shields to (Strain1 and Strain2 connectors) of the second (topmost) Wheatstone shield. Is this right?

How does A0, A1 connection to A2, A3 help this?
regards
Sachin
