This is a little video showing what I've been working on recently, well two things. One is a quick program I wrote in Java that converts RTTTL ringtone code to Arduino audio code. The second, the circuit, takes the standard square wave output by the digital pins on the arduino into something more palatable for the ear. The RC circuit makes the wave into something more curvey and sine wavey.
