+First, you need to configure the component with the digital pins that control the multiplexer.
 Then you need to set up a voltage sensor source (e.g. :doc:`ADC sensor <adc>`) and pass it to the cd74hc4067 sensors with the ``sensor`` option.
 Each cd74hc4067 sensor is configured for one of the 16 input pins of the multiplexer.
