    Try the BASIC Stamp Manual. You can download it from www.parallax.com -> Downloads -> Documentation.

    There are also some interesting FREQOUT applications that you can try with your Boe-Bot's piezospeaker in What's a Microcontroller, Chapter 8.· What's a Microcontroller is available for download from www.parallax.com -> Downloads -> Stamps in Class tutorials.

    Sorry, no, there's nothing about harmonics in the BASIC Stamp Manual.

    I'll have another post for you in a bit. The short answer is that speakers are always like filters (woofer, midrange and tweeter) all filter for a particular sound frequency. So it would be rather difficult to broadcast the harmonic with a speaker (unless you are using an ultrasonic speaker). Infrared broadcasts it, and so will a wire.

    I posted a more in depth explanation in a new Stamps in Class forum thread entitled About Freqout and Boe-Bot IR Detection.
