class BBB::Components::AnalogComponent
An AnalogComponent
is a component that reads from an analog input (AIN) on the board. You can use a generic analog component for, for example, temperature or light sensors.
The BeagleBoneBlack has 12 bit (4096) AIN pins. So the expected value of an analog pin is between 0 and 4096.
