SmartButton

An advanced, event-driven button debouncing library for Arduino. It uses a non-blocking FSM (finite state machine) and supports click, double click, long press, and custom callback commands using the Command design pattern.

🔧 Features

• Clean, modular design with OOP principles
• Fully non-blocking: perfect for responsive applications
• Customizable callback support via ICommand
• FSM-based internal logic for robust state handling
• Click / Double Click / Long Press / Hold support
• examples/SmartButtonDemo.ino provided

📦 Installation

Option 1: Download and extract to Documents/Arduino/libraries/SmartButton/

Option 2: Add to Arduino IDE using .zip file via:

Sketch > Include Library > Add .ZIP Library...

🚀 Getting Started

#include <SmartButton.h>
#include <CallbackCommand.h>

SmartButton button(2);

void onClick() {
  Serial.println("Clicked!");
}

void setup() {
  Serial.begin(9600);
  button.setClickCommand(new CallbackCommand(onClick));
}

void loop() {
  button.update();
}
