Recently, a friend of mine had an issue with his car’s ECU and needed a frequency counting device.
In this Tutorial we will learn how to make a Frequency Signal Generator using a AD9850 module and Arduino.
This frequency meter uses an inexpensive STM32 microcontroller, and the frequency range is from 0 to 30 MHz
Measure and record mains frequency on the SD card along with the timestamp.
In this tutorial we will learn how to make a simple Frequency Counter using Arduino. Watch the video!
AC Line frequency (50Hz / 60Hz) has small fluctuations in the short term, but is compensated daily resulting in a quite accurate reference.
This Astable multivibrator is used to generate the PWM signal. Basically a rectangular signal of variable duty cycle and frequency.
Cheap and Easy-to-build function generator which delivers great performance with sine, triangle, and square waveforms.
Will introduce about the Red Pitaya and it's capabilities.
This is a breadboard-compatible clock generator module that outputs stable square waves from 0.5 Hz to 2048 Hz.
This device allows doctors to assess the severity of hand tremors by providing quantitative statistics on the tapping frequency.
