In this project, the Arduino Uno is configured as a square wave generator with user-selectable control of the frequency and duty cycle.

In this tutorial, T.K. Hareendran shows us how to set up an interleaved PWM output on an Arduino Uno. He then uses different techniques to validate that the desired result is achieve.

Tsunami is a signal generator built on the Arduino platform. It is the brainchild of London-based developer Nick Johnson at Arachnid Labs.

ERAsynth is an open source, crowd-funded project — now available on Crowd Supply — aiming to make multi-GHz RF signal synthesis accessible to everyone. Remarkably, the ERASynth from ERA Instruments ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

A fully fledged spectrum analyzer on a basic Arduino board? It is possible when the software is tailored to the available processing power. A standard Arduino can be turned into an AC line (‘mains’) ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially ...
