I see examples of oscillators and astable multi vibrators online and they're all capable of generating sound because... they oscillate obviously.
What I haven't been able to find is advice on how to best connect a breadboard oscillator (whether from a 555 or an opamp) to the Line-In of a computer safely and without clipping.
I've plugged the output of Pin 3 of a 555 running of 4 AA batteries into the Line-In of my old computer and I had to turn that input down to 1 (as low as it goes) to have it not clip.
Is it as simple as just adding a resistor or a pot to the signal going into center pin or ring of the 3.5mm connector?
I have a nice stereo 3.5mm TRS jack I unsoldered from something that plugs perfectly into a breadboard so that's handy.
Now that I've messed with the 555 a bit to make sounds I'd love to make a VCO with an LM324 or LM358 but I want to make sure I've got a good audio output to run them into a computer.
