Arduino/Arduinomorse Library
From charlesreid1
The first step is to download the arduinomorse library from GitHub: https://github.com/markfickett/arduinomorse
The second step is to zip up the resulting folder into a zip file, arduinomorse.zip.
The third step is to load this as a library in the Arduino development environment, which will add the relevant header files to somewhere where Arduino will find them when you #include them.
