Tone Generator

A project log for Puff-Suck interface for fast text input

A tube connected to a bipolar pressure switch drives an Arduino which translates puffing and sucking into Morse code and then into text.

Currently, an LED flashes for Morse code, but visual feedback is not good enough. To Morse quickly, you need to have sound feedback. Cat and I will need to find a suitable speaker and turn it on at the same time as the LED, and I'm also working on a way to change the speed at which you Morse.

The Arduino tone() function seems to be good for our purposes, but it does use a timer, so I wrote the code and ran it without connecting the speaker, and it still seems to work fine.
