An Arduino C++ library that detects single clicks, double clicks, and long presses from a single pushbutton attached to one digital input pin, allowing one button to serve multiple input functions. It uses a non-blocking tick() function and a finite-state machine, with a lightweight OneButtonTiny variant for small processors.

Use cases

• detect single, double, and long button presses on Arduino
• use one physical button for multiple functions
• debounce a pushbutton without blocking the main loop
• attach callback functions to button press events
• read button input on ATtiny microcontrollers with limited memory

When to choose

• you have limited input pins and want one button to trigger multiple actions
• you need non-blocking button event detection in an Arduino sketch
• you want simple debouncing and click/press event callbacks out of the box

When to avoid

• you need multi-button matrix scanning or touch input
• your project is not on an Arduino-compatible embedded platform
