The combinator allows 4 load-cells to be combined (in a Wheatstone bridge config) and then connected to the amplifier board (HX711).

But how does this work? Let's say the load-cells all start at the same resistnace, and there's one in each corner of a scale platform. If the weight is then applied to the center of the platform, such that each load-cell gets the same incremental weight, then their resistance change will all be the same, and the Wheatstone resistor-dividers each still have the same voltage they had before the weight was applied....

How does that allow you to to measure the applied weight? Ugh.....

tnx,
