Morse code is an old method of character encoding used to transmit messages via telegraph. Morse code mainly consists of dots and dashes that correspond to electrical tone length. Anyway Morse code is only used by radio amateurs now and is more fan than practical in such technology age. If you want to learn Morse code – why do this in old fashioned way… make it more computer friendly. Next project is a Morse keyboard that has old fashioned taping device connected to AVR ATmega168 microcontroller with software USB implementation.
Device is recognized as standard USB keyboard and can be used to input text by taping Morse code. Sounds fun, isn’t it? Also device has dual 7 segment LED indicator that indicates typing speed in Words per Minute (WPM).
