A frequency counter using an Arduino as a micro controller and a DS3231 as a reference time source - alan-od/Arduino-Frequency-Counter ...

Note: This counter is based on chip 74xx93 (counter) used as a frequency divider by 8 the maximum bandwidth for arduino to count is 8 Mhz and we can multiply this number using 74xx93 or any other ...

Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum fr… ...

When looking to port over a frequency measurement library he ended up writing his own that works better and is much more portable. He had two big beefs with the Arduino Frequency Counter Library.

French developer is looking for support amongst the Arduino community for his crowd-funding project – an Arduino compatible high precision frequency counter. Thierry Guennou, writes: “The concept of ...

Now we can use the “Arduino Frequency Counter Library,” which makes it possible to measure frequencies with a high resolution and accuracy. In this library, the frequency input is fixed to Digital Pin ...

This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in digital signal processing (DSP) and electronics labs. The author ...

And what's a geiger counter without ominous clicking? The Arduino microcontroller counts the pulses per minute. Using this measurement the microcontroller calculates Sieverts per hour.
