ESP8266 and ESP pin interrupt example

This Arduino sketch implements properly a simple pin change interrupt on any ESP microcontroller (ESP8266 and ESP32).

Note that it's not using any debouncing, for buttons it's better to use any dedicated library. It's only a correct implementation example.

Configuration

You can change test pin changing BUTTON_PIN define.

It's configured as INPUT_PULLUP, so to trigger it you have to connect it to ground.

Compilation

You can compile the sketch using Arduino IDE with ESP8266 or ESP32 support.

Usage

Input pin is configured as INPUT_PULLUP, so to trigger it you have to connect it to ground.

It will differentiate between short and long press (> 1s pressed).

Hardware

No extra hardware is needed, except for power supply and a cable to connect input pin to GND.
