Simple Function Generator Wiring diagram Schematic using NE566

Simple schema function generator that generates square wave and triangular or sawtooth. The frequency is determined by R and C1. For the sawtooth wave output is on pin 4 and the voltage of 6 V, while for the square wave output is on pin 3. The function generator schema uses only one 566 and can be connected to output amplified audio. The frequency is set by potentiometer R2.
