 The HX711 amplifier allows you to easily read load cells and evaluate changes in resistance. A Wheatstone bridge is used to connect load cells to the IC, which is in turn connected to the microcontroller via `VCC`, `DT`, `SCK`, and `GND`. Use `begin()` to initialize the scale and `set_scale()` and `tare()` to calibrate it. `power_down()` and `power_up()` can be used to bring the ADC into and out of low power mode. `get_value()` and `get_units()` are used to read the ADC minus tare and divided, passing an optional integer value to obtain that number of values, averaged. Refer to the [`HX711` Arduino library](https://github.com/bogde/HX711#features) for more details on features and calibration.

+## Automation controls
+
+The HX711 can be controlled using [Automation Scenarios](../wokwi-ci/automation-scenarios). It exposes the following controls:
+
+| Control | Type  | Description                             |
+| ------- | ----- | --------------------------------------- |
+| load    | float | Set the load value of the scale (in kg) |
