The Magic Morse algorithm is copyrighted, but he has released the Arduino code as open source in an effort to get people using Morse code once again — it is pretty awesome. So how does it work?

Arduino Morse Trainer is an open-source Morse code transmitter and decoder with a 4x20 LCD, adjustable speed, and real-time feedback via buzzer and LED. Includes I2C and parallel LCD support, a 3D- ...

Morse Code Translator This project is a simple yet effective Morse code translator built with C++, designed to convert text input into Morse code using an Arduino-based setup. The translator takes ...

They even decoded some Morse code messages and used the device to practice on it. After a while they’ll easily be able to master the Morse code trainer!

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.
