// Instantiate a Bounce object
Bounce debouncer = Bounce();

// Setup the button with an internal pull-up :
pinMode(BUTTON_PIN,INPUT_PULLUP);
// After setting up the button, setup the Bounce instance :
debouncer.attach(BUTTON_PIN);
debouncer.interval(5); // interval in ms
//Setup the LED :
pinMode(LED_PIN,OUTPUT);
}
void loop() {
// Update the Bounce instance :

// Get the updated value :
int value = debouncer.read();
// Turn on or off the LED as determined by the state :
if ( value == LOW ) {
