What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino? [Brett Killion] did make that combination and wound up with a practical network analyzer.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

A radio, of course! Well, the project presented here is about building a compact Arduino FM Radio with the help of an astonishingly cheap (eBay) radio module. Recently, I built one for my needs and ...

The Arduino Portenta Mid Carrier and the Arduino Pro 4G Module are the newest additions to the Arduino Pro range, designed to enhance your projects with unparalleled connectivity and prototyping ...

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386. A single button on the Arduino helps cycle ...
