Implements knobs that request for confirmation before setting the value.
Behavior is as follows:
On startup, the first value read from the knob is taken.
When the user adjusts a value past a threshold from the current value the corresponding value blinks on the display with the new value but the new value is not taken until the user hits the confirm button.
If the user does not press 'confirm' for 5 seconds, an alarm goes off showing the previous and the new value and requesting the user to confirm if the new value should be set.
If the user returns the knob to original position the alarm turns off and the blinking stops.
