This is an Arduino library that enables you attach an interrupt to any pin of Arduino Uno, Nano, Mini and other 328-based boards. The Arduino attachInterrupt () function only allows pines 2 & ~3.

Version: Arduino IDE 1.8.19, Arduino Mbed OS Nano Boards 2.8.0 attachInterrupt incorrectly resets the mode of an input pin back to the default pull mode (INPUT_PULLUP). This silently overrides an ...

Here a function called attachInterrupt is used, which will configure digital Pin 2 of Arduino as an external interrupt and it will call the function named coinInterrupt, when it detects any interrupts ...
