This circuit works like a wave generator, in sequence the sine, square, sawtooth and triangle waves.
The point of this circuit is offer a very low cost possibility to generate those waveforms, and of course the circuit can be further beef up!
Also, the 1M resistor is just for the simulation kicks in, not necessary in a final circuit.
Saddly, the frequency isn't ajustable.
Please wait the waves on the osciloscope to kick in before playing with the potentiometers, if the simulation breaks, reload...
