MorseCodr is a program for practising Morse code communication. You can connect to other users and send Morse signals that are automatically interpreted by the program. Once you become more proficient, you can reduce the amount of display and interpretation provided. It features Morse code tape display, dot/dash colouring, letter interpretation, and adjustable speed.
Sam is a Morse code trainer. It is a bash script that runs in a terminal. It beeps and boops out the command-line arguments in Morse code. If there are no command-line arguments, then it beeps and boops the Usage message. Simple, no? But the gimmick is that it prints out the text to the terminal, and the cursor below the text keeps track of which letter is being sounded.
