HAM radio operator and Arduino enthusiast WB7FHC has written a great tutorial on how to program an Arduino to decode Morse code. Apart from being an interesting exercise in Arduino programming, it could be useful for the tired (or lazy?) DX'er who needs to keep track of various code transmissions. Although the project sends the results to the Serial Monitor, it could easily be modified for an LCD and thereby making the unit portable. Here is an example of operation:
To get started, work through the detailed tutorial here. And we're on twitter and Google+, so follow us for news and product updates as well.
To easily convert projects like this for portable use with an LCD, consider our Freetronics LCD Keypad Shield, which contains a bright 16x2 character LCD and five buttons that can be read from only one analog input pin:
