I'd like to use an LM324AN to make a VCO.
I've found lots of good videos, websites and applications to help with 555 circuits (and created square waves and something saw-like) but not much for Opamps.
Does anyone know of a good tutorial or video that could show me how to build something like the VCO on page 13 of the National Semiconductor LM324 datasheet under "Typical Single-Supply Applications"? Even the simpler Squarewave Oscillator on page 11 would be a good start.
I know there are many different opamps with different specs unlike 555s which are pretty much all the same so it complicates things when giving advice on how to make oscillators with them.
