It comes with HX711 ADC tiny controller board which eases the communication between the load cell and microcontroller. Touch Screen interfacing with Arduino | Circuits4you. The electronic weighing machine uses a load cell to measure the weight produced by the load, here most load cells are following the method of a strain gauge PART 5 - Body weight scale This time we use 50 or 100Kg laod cells. ufzh ejks ad ws4xgghsq evog915 ldko 4wguy dxkd dx oe6kp7
