// SimpleWithLibrary example sketch for the EnableInterrupt library. Demonstrates how to use
// the EnableInterrupt library with a sketch that services an interrupt pin, and uses a library
// that also requires the EnableInterrupt library.

// This sketch has only been compiled to the Arduino Uno (ATmega328).
// This sketch is only known to compile. It has not been tested functionally.

// See https://github.com/GreyGnome/EnableInterrupt and the README.md for more information.
