"""
This example shows how to use the ModulinoKnob class to read the value of a rotary encoder knob.

The knob is used to increase or decrease a value. The knob is rotated clockwise to increase the value and counter-clockwise to decrease it.

You can register callbacks for the following events:
- Press: The knob is pressed.
- Release: The knob is released.
- Rotate clockwise: The knob is rotated clockwise.
- Rotate counter clockwise: The knob is rotated counter clockwise.

Use reset() to reset the knob value to 0.
