Arduino Kitchen Scale (HX711 + Load Cell + I2C LCD)

Put the bowl on, press the button, zero! A real kitchen scale with an **HX711** amplifier and a 5 kg **load cell**: the **I2C LCD** shows the weight in grams or ounces, with a fill bar on the second row. One **button** does two jobs: a short press tares, a long press switches between g and oz. At 5 kg an overload warning appears. Calibration, a moving average and short/long presses in one project.
