Although the requirement to understand Morse Code has now been removed from amateur radio licensing requirements in some areas, the use of Morse is still quite popular and many people enjoy experimenting with low power CW or the challenge of communication. Learning from scratch in the past involved playing and repeating codes from practice tapes, but now you can bring this into the 21st century with Arduino.
Enthusiast Ray Burne has created a small device that can be used to test your keying including spotting errors and calculating your keying speed. The device can be built around various Arduino and compatible boards, and thus easy to replicate if required.
