Since so many people were having problems with the INA125P, we now have a new and improved version that uses the Hx711 24bit ADC amplifier module. http://arduinotronics.blogspot.com/2015/06/arduino-hx711-digital-scale.html
My goal was to create a programmable scale for weighing objects, parts counting, even directing product flow on a conveyor system.
I needed a load cell, a Arduino, and an amplifier.
Step 1: The Load Cell
Red: Excitation +
White: Signal +
Green: Signal -
Black: Excitation -
This matches the GSE / NCI / Sensotec wiring scheme.
I disconnected the 4 wires from the control board in the scale, so they would be available for the next step.
