Compatibility

This library is compatible with the samd architecture so you should be able to use it on the following Arduino boards:

Releases

To use this library, open the Library Manager in the Arduino IDE and install it from there.

Usage

This library allows an an Arduino based on SAMD architectures (all MKR boards, Nano 33 IoT and more) to sample an analog Input signal and get back its frequency. The analog pin to be used to sample the signal and the sample frequency can be chosen.

To use this library:

#include <AudioFrequencyMeter.h>
