Everyone needs a good scale in kitchen, what better than to build a high precision scale with the UNO?

I'm really surprised too. I work in scale industry, everyday I can test 1k € scales and more. I've made some digital filters and I have reach almost the same accuracy.
With a c6 class load cell it would be even better!
I've never seen load cells with 3 wires only except digital ones that uses CAN bus to communicate (Can high,can low and shield Gnd)
I think that are a sort of a current partitore. You can power one and check if something change between output and GND.
Hi! I made a 0.2/0.5 multi division scale. It's quite good considering that I use a C3 class load cell only and an hx 711.
