Tap code trainer

This is a trainer I made for me and my friend for decoding tap code. Make sure to have sound turned on, then use the button to play one letter at a time. When the whole word is revealed, a new one will be chosen randomly.

Every letter is knocked in two groups, first y, then x. This means the first column can be memorized and counted along during the first group, and then the following part of the alphabet can be counted during the second, to get to the letter that's knocked.

C (. ...) also represents K, because there isn't enough space for all 26 letters.
