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 measured by the library spans from 60 to 1500 Hz and …
Frequency Counter - Arduino Project Hub
https://create.arduino.cc/projecthub/moty/frequency-counter-92ec57
The Arduino generates an accurate 1 second time base for the counter by cascading timer0 and timer2. The link between digital inputs 3 and 4 connects the output of timer2, 250 Hz, to the input of timer0. The software waits for the output of timer0 to go positive to start the count of frequency input to timer1.

Arduino frequency counter circuit: Project circuit diagram is shown below. The 16×2 LCD screen (2 rows and 16 columns) is used to display the values of frequency and period of the input voltage where: RS —> Arduino digital pin 2 E —> Arduino digital pin 3 D4 —> Arduino digital pin 4 D5 —> Arduino digital pin 6 D6 —> Arduino digital pin 7
Arduino - AudioFrequencyMeter
https://www.arduino.cc/en/Reference/AudioFrequencyMeter
This library allows an an Arduino based on SAMD architectures (i.e. (i.e Zero, MKRZero or MKR1000 Board)) 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> Examples. Simple Audio Frequency Meter

With that in mind we are going to design a simple yet efficient Frequency Counter using Arduino Uno and Schmitt trigger gate. This Arduino Frequency Counter is cost effective and can be easily made, we are going to use ARDUINO UNO for the measuring the frequency of signal, UNO is the heart of project here. To test the Frequency Meter, we are going to make a dummy …
