A simple but beautifully accurate PWM frequency meter.
Arduino OLED dual channel oscilloscope with 16Msps equivalent time sampling, Pulse Generator, DDS Function Generator and Frequency Counter
Timer one is used in this code and using this the Arduino crystal clock is divided into various small parts microseconds are used for freq.
I needed a small, cheap frequency counter. It would be the frequency display of my planed signal generator.
A tiny frequency meter built using the ATtiny1614 microprocessor.
Learn how to make a Pulse Generator with a Frequency Sweep.
This project describes a short range metal detector useful for positioning proximity and robotics
How to build a Sine Wave Oscillator with Frequency Meter using kits purchased online.
Find out how to design RPS Counter to count revolutions of rotating objects
Built & compared two PLL frequency synthesizers: classic 7493 TTL vs. programmable PIC microcontroller. PCB, simulations, and lab report.
In this project, one Arduino produces two frequencies and another counts two frequencies, both independent from each other.
Oscillators are very precise nowadays, but will they be exact? This is to compare two UNOs.
