Will I ever stop demoing this 555 sequencer? Probably, but maybe not.
However, this would be as good a stopping point as any. This time, I added three potentiometers in place of the normal resistors -- which lets me vary the pitch of each of the three notes far more easily than before.
In case you're wondering why I keep hammering away at this project, it's because I'm getting it to be somewhat presentable for the 555 Contest -- a contest based on the 555 timer, started/organized by Jeri Ellsworth. Unlikely that I'll win any awards for my project, but at least I can get a sense of accomplishment out of it. =)
