I'm working on a site called Morse Code Guru. This is going to be an interactive app that will teach people how to send and receive Morse Code.

I just launched a demo of some of the morse code logic at www.morsecode.guru. The tricky part of this was breaking down the lengths of clicks into 'dots' and 'dashes', and then into English. 

The sound is achieved using an oscillator node with the web AudioContext. I'll likely need to add sound controls and maybe the ability to change the pitch.

A lot of the logic for the lessons is also ready, so mostly what's left is writing the educational material.
