Arduino library to debounce button switches, detect presses, releases, and long presses

Arduino library for debouncing momentary contact switches, detect press, release, long press and sequences with event definitions and callbacks.

An adjustable, compact, event-driven button library for Arduino that debounces and dispatches events to a user-defined event handler.

Arduino library for button debouncing.

This project is to implement a combination lock on the FPGA board using VHDL language and finite state machine. There are some possible solutions are provided to address the problems including debounce, random number generation and combination check.

Long button press detect and debounce for the ESP8266-based SonOff Basic WiFi smart switch.

Advanced Debouncer Library for Arduino

Arduino library for push buttons at INT0 and / or INT1 pin (pin 2 / 3). Provides debouncing and toggle button functionality.

Button is a class for (debouncing) button queries. The included ButtonSL is extended so that a distinction can be made between a short and long button press.

Complete buttons to switches library implemented for ESP32-Arduino, with flags update automation, function callbacks, tasks unblocking, task resumes, all encapsulated in classes sharing a common API for simplest implementation, use, modification or replacement when needed.
