Simple Audio Frequency Meter | Arduino Documentation ...
https://docs.arduino.cc/tutorials/zero/simple-audio-frequency-meter/
AUTHOR: Arduino. LAST REVISION: 01/18/2022, 10:24 AM. This tutorial explains how to use the Audio Frequency Meter Library for Arduino Zero boards. The code uses a method of the library to measure the frequency of a signal connented to A0 and amplified through an electronic circuit, in order to get the frequency of a generic input signal. The range currently …

The audio input to the Arduino is on A0, with bias at the mid point by 10K to Ground and 10K to +5V. At the input we can also set a potentiometer to control the amplitude of the input signal. Code is also simple and it uses "fix_fft" libray which was created for this purpose.
