void invert()
Invert the analog value.
void resetToCurrentValue()
Reset the filtered value to the value that's currently being measured at the analog input.

Get the filtered value of the analog input with the mapping function applied as a floating point numb...
bool update()
Read the analog input value, apply the mapping function, and update the average.

A super class for object that have to be updated regularly.
A class for controlling the volume of AudioMixer4 objects using a potentiometer.
VolumeControl(const Array< AudioMixer4 *, N > &mixers, pin_t analogPin, float maxGain=1.0)
Create a new VolumeControl object.
Array< AudioMixer4 *, N > mixers
void update() override
Read the potentiometer value, and adjust the gain of the mixers.
void map(MappingFunction fn)
Specify a mapping function that is applied to the raw analog value before setting the volume.
void begin() override
Initialize.
void invert()
Invert the analog value.
