Arduino: second verse, same as first… sort of

well, not really. feeble attempt and making some sort of microprocessor controlled tempo clock, but a good exercise in the ATMEGA328s finicky behavior. don’t ask me what that squeal is. i think it comes from the way the input was wired up (mistaking the second sleeve as a synonym for ground) coupled with the PWM stream not having a negative offset, but who knows. eventually, i’ll move off the tone() crutch and start working with more interesting DSP. it’ll be nice to start using some of the memory on the chip.

i will also post the schematic for the delay pedal once i’ve got the values i want in it. i won’t have any time nor tools to tear into it until next week though.
