MultiClick

A simple Arduino library that makes it eazy to detect single, double and long clicks..

OBS! This project is under development, more precise the debounce is not implemented yet. Everything else works. OBS!

Tested hardware

• NodeMCU V1.0 / ESP8266: Works!

How to use

First download and install this library in your IDE and include it in your sketch by typing #include <multiClick.h> at the top of the document.

You can then create an object of the MultiClick class with it's constructur that can take four arguments but only the first one (pin) is required, the other are optional and have default values (see below list).

MultiClick button(int pin, int debounce_t, int double_t, int long_t)

• pin is the pin of the button that you wanna use (required)
• debounce_t is the button debounce time in ms, default 20 (optional)
• double_t is the max time between two clicks that should register as a double click, in ms, default 250 (optional)
• long_t is the minimum time from that a button is pressed down to that a long press action is fired, in ms, default 1600 (optional)

There are tree functions that let's you set your callback function for when the different events are created, .setSingleClickFunction, .setDoubleClickFunction and .setLongClickFunction. They all take a function as a argument.

At last. The .tick() method needs to be run inside you main loop. Be aware tho, for the best performance, you should not use any delay/sleep methods in your loop as this will make the buttons feel more unresponsive.

Example

#include <multiClick.h>

MultiClick button(12);

void setup() {
  Serial.begin(9600);
  button.setSingleClickFunction(singleclick);
  button.setDoubleClickFunction(doubleclick);
  button.setLongClickFunction(longclick);
}

void singleclick() {
  Serial.println("Single click just happend");
}
void doubleclick() {
  Serial.println("Double click just happend");
}
void longclick() {
  Serial.println("Long click just happend");
}

void loop() {
   button.tick();
   delay(10);
}

Now open your serial monitor at baudrate 9600 and click the button you have connected to pin 12!
