Speaking of sound, I played around with a BASIC stamp kit[1] and it was pretty cool that it supported polyphonic sound[2] easily, so I was able to program music with harmonies on it right away. It's also fun for creating DTMF signals such as dial tones, busy signals, and dialing numbers. (Personal note: I've had a lot of fun doing sound on computers from the PC speaker (1 voice square wave), to the SAA1099 as found on the Game Blaster and optional add on for the Sound Blaster (12 voices square wave, 6 per chip), the BASIC stamp mentioned above, or most recently generating wave forms with math (adding sine waves together) and outputting it to DirectX which I learned from Handmade Hero day 007 through 009.[4]) [1] This one exactly: https://www.parallax.com/product/90005 https://www.parallax.com/product/90005 [2] Two frequencies per pin with FREQOUT command: http://www.parallax.com/go/PBASICHelp/Content/LanguageTopics/Commands/FREQOUT.htm http://www.parallax.com/go/PBASICHelp/Content/LanguageTopics...
