I'm trying to construct a sort of instrument that can play things I draw in pencil. I've included a picture of the protoboard setup. The output to the speaker is a square sine. But for the purpose it's being constructed for, I really need a sawtooth coming out. I've toyed around with some different ideas, but don't really know what I'm doing. Also, I need the sawtooth wave to vary in pitch just as the square would when I change the resistance in the circuit by touching the graphite strip in different locations.
Any help is very, very greatly appreciated.
