Fubarino Contest: Morse Code Transmitter

The Fubarino Contest entries are slowing streaming in. Here’s the first one that we’re featuring, sent in by [Nathanael Wilson]. He dusted off a project from some time ago, which is just fine with us. It’s a Morse Code transmitter which he designed for use during a fox hunt (locating a hidden transmitter using radio direction finding).

For the project he revised his old code, adding in a Morse look-up table so that the Arduino Mega 2560 can convert plain text into dots and dashes. It uses the tone library to output signals to the radio seem above. The easter egg is unlocked when shorting pin 10 at power-up. It then broadcasts a slightly altered message as interpreted above.

One of the reasons we chose to feature [Nathanael's] entry first is that he presented it very well. Watch his video after the break to see for yourself. Then go back and check out the contest rules to get your own project submission in. After all, you can win a free Fubarino board from Microchip if you’re in the top twenty!
