https://www.electronics-lab.com/project/audio-oscillator-with-frequency-counter/
Audio Oscillator with Frequency Counter. This project is not completely new. In fact, the oscillator is made from the same schematic as in one of my previous projects and only the frequency counter is made with different schematic. After I finished the oscillator, I made some minor changes in the square signal part of the schematic.
