An Arduino running Morse code converter software controls the boost convert and LED. [Yannick] uses his computer to send a message over the Arduino’s serial link, and the light does the rest ...

This project uses two Arduino to communicate with each other using light by means of Morse Code. As a more advanced project, it has some complex array usage and investigates converting switch inputs ...

But even if constructing a Morse code trainer is beyond your skill set, it’s still cool to know people are still inspired by the nearly 180-year-old system.
