This project generates a square wave signal using Timer1 on an Arduino. The frequency of the square wave can be adjusted via serial input, making it a versatile tool for signal generation and testing.

The arduino nano sends the waveform type and frequency via SPI to the AD9833, that generates the requested waveform. While doing this, the OLED display (SSD1306) is updated by the arduino via I2C, ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. There’s ...

Abstract: The learning of multi-frequency signals, such as modulated signals or noise-distorted signals, is usually done with the help of simulation. However, not all of the signals generated by a ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

I was recently working on an experiment for a new design and was using a function generator. Although new function generators have pretty good frequency tolerance specs, I needed something with more ...

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 ...
