SMS to Morse Code with Adafruit FONA

Devon Elliot has a great blog post that describes how he re-purposed a vintage telegraph sounder to sound out tweets and SMS messages with an Arduino & Adafruit FONA.  Telegraph sounders were used in the early days of wired communication to sound out the dits and dahs of morse code and they worked with an electromagnet much like a mechanical relay.  Devon describes how he wired up a telegraph sounder to an Arduino and then connected an Adafruit FONA to allow SMS messages to be sounded out as morse code.  Fantastic work!
