It is a very simple build a simple Audio-oscillator Circuit Diagram
Project. The circuit`s frequency of oscillation is/= 2.8/ [C1 x (R1 +
R2)]
. Using the values shown, the output frequency can be varied
from 60 Hz to 20 kHz by rotating potentiometer R2. A portion of IC1`s
output voltage is fed to its noninverting input at pin 3.
Audio Oscillator Circuit Diagram:
The voltage serves as a reference for capacitor Cl, which is connected
to the noninverting input at pin 2 of the IC. That capacitor continually
charges and discharges around the reference voltage, and the result is a
squarewave output. Capacitor C2 decouples the output.
