Audio Frequency Detector - Arduino Project Hub
https://create.arduino.cc/projecthub/lbf20012001/audio-frequency-detector-617856
This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is then performed on the …

https://www.instructables.com/Arduino-Frequency-Detection/
As a follow up to the Arduino Audio Input tutorialthat I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino's analog input and determines the frequency. The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes. I've also turned the LED attached to pin 13 into a clipping indicator, so you know if you need to adjust your signal's …
