+ DESCRIPTION
+ ====================
+ Simple example of the Bounce library that switches the debug LED when
+ either of 2 buttons are pressed.
+ */
+
+// Include the Bounce2 library found here :
+// https://github.com/thomasfredericks/Bounce2
+#include <Bounce2.h>
+
+#define BUTTON_PIN_1 2
+#define BUTTON_PIN_2 3
+
+
+#define LED_PIN 13
+
+// Instantiate a Bounce object
+Bounce debouncer1 = Bounce();
+
+// Instantiate another Bounce object
+Bounce debouncer2 = Bounce();
+
+void setup() {
+
+ // Setup the first button with an internal pull-up :
+ pinMode(BUTTON_PIN_1,INPUT_PULLUP);
+ // After setting up the button, setup the Bounce instance :
+ debouncer1.attach(BUTTON_PIN_1);
+ debouncer1.interval(5); // interval in ms
+
+ // Setup the second button with an internal pull-up :
+ pinMode(BUTTON_PIN_2,INPUT_PULLUP);
+ // After setting up the button, setup the Bounce instance :
+ debouncer2.attach(BUTTON_PIN_2);
+ debouncer2.interval(5); // interval in ms
+
+
+ //Setup the LED :
+ pinMode(LED_PIN,OUTPUT);
+
+}
+
+void loop() {
+ // Update the Bounce instances :
+ debouncer1.update();
+ debouncer2.update();
+
+ // Get the updated value :
+ int value1 = debouncer1.read();
+ int value2 = debouncer2.read();
+
+ // Turn on the LED if either button is pressed :
+ if ( value1 == LOW || value2 == LOW ) {
+ digitalWrite(LED_PIN, HIGH );
+ }
+ else {
+ digitalWrite(LED_PIN, LOW );
+ }
