Dual action button

This sketch demonstrates the basic implementation of a dual action pull-up button or switch, that differentiates between a short and long press.

The code

#include <CtrlBtn.h>

// Define an onRelease handler.
void onRelease() {
  Serial.println("Short press");
}

// Define an onDelayedRelease handler.
void onDelayedRelease() {
  Serial.println("Long press");
}

/*
  Create a button with:
  - signal pin.
  - bounce duration.
  - empty onPress handler (nullptr).
  - onRelease handler.
  - onDelayedRelease handler.
 */
CtrlBtn button(1, 15, nullptr, onRelease, onDelayedRelease);

void setup() {
  Serial.begin(9600);
  button.setDelayedReleaseDuration(1000); // This is optional (default is 500ms).
  // If you use an external pull-up resistor, uncomment this:
  // button.setPinMode(INPUT, PULL_UP);
  // If you use an external pull-down resistor, uncomment this:
  // button.setPinMode(INPUT, PULL_DOWN);
}

void loop() {
  // The process method will poll the button object and handle all it's functionality.
  button.process();
}
