So i got a simple 40106 oscillator set up, which is pin 14 to 9v, pin 7 to GND, 0.1 uf decoupling cap between 14 & 7, pin 1 to ground through a 0.1 uf cap, 100k resistor between pin 1 and 2 and finally, and a 10k resistor from the pin 2 output (similar to the screenshot below)
The pin 2 output of the 40106 is then going through a B10k potentiometer (variating the output amount) into the input of an LM386 (9v powered) amplifier circuit which is modelled on these two Youtube videos from the same dude:
The LM386 circuits works great IMO (outputting into an 8ohm speaker). However, when i adjust the B10k potentiometer to change the volume, the pitch that the 40106 is producing changes also. Is there a way I can isolate the two to prevent this. Any help would be hugely appreciated.
P.s I am a total amateur.
