Arduino Serial References

One of the things that I'll need to explain is asynchronous serial communication, which is how the arduino communicates to the FTDI chip (or other serial devices) to communicate to a computer via USB. I found some resources for arduino Serial stuff (including an article about using PWM for servo motors so that the software serial library doesn't get screwed up by the current servo library's use of interrupts).

There's a good wikipedia article about asynchronous serial.

There is also the arduino description of the software serial library, which is useful for describing how serial works (and how to make it work without hardware serial).
