/*
  This example sets up a debouncer for a set button and a reset button to control the state.
  - Declare a debouncer for the set button with delayed mode for debouncing.
  - Declare a debouncer for the reset button with instant mode for debouncing.

  Both set and reset buttons have a debounce period set to 1 second.
  - To set the state, press the set button for 1 second.
  - To reset the state, press the reset button for an instant reset.

  The LED_BUILTIN will reflect the state value.
