Let your Arduino speak morsecode
This library let you use morsecode in your programs. It can both beep directly with an attached speaker or toggle a pin to "key" an external beeper or transmitter.
Use it as an keyer for hamradio or use it like an "display" to "print" results or status. Remote controlled gadgets can tell you their status over an simple telephone line.
To install, find the directory used by Sketch > Import Library and unzip the file into that directory. The library will then show up in Sketch > Import Library. See sourcecode for the library interface details.
Downdoad the library from http://code.google.com/p/arduino-morse/
The library is based on code created by Mark VandeWettering, K6HX
