Morse decoding using Arduino

Here’s a quick hack I keep meaning to release in a meaningful way: a morse code decoder in arduino.  Hook up a button to pin 2 (like you would for the button examples), and then watch the serial monitor.  If you key in SOS (…/—/…), it will light up the LED on pin 13.  My intention here was to use this to buzzy myself into my apartment building’s door, but I still haven’t gotten around to actually putting it inside the box yet(!).

Give it a go, and see what you think of it.  I’d also like to hook it up to an LCD panel and make a proper morse training device out of it, but that’s for another day, I think.

Leave comments here if you make any use of this, I’m keen on seeing what happens with it!
