[Jan] decided to build something better and cheaper using a 32-bit Arduino and a DDS frequency generator chip on a breakout board. Oddly enough, the device doesn’t have a display.

The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

Features of the DIY function generator Arduino project include: ... – Output frequency: Available range from 0Hz to 10MHz, providing a wide range of testing capabilities.

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the ...

The board has been tested with an Arduino Uno. It can measure frequencies from less than 5Hz to above 70MHz. Low frequency signals (LF), high frequency signals (HF) and very high frequency signals ...

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.

Tsunami is a signal generator built on the Arduino platform. It is the brainchild of London-based developer Nick Johnson at Arachnid Labs and has secured funding on Kickstarter for its commercial ...
