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.

Arduino Sensors using Omron D6T Non-contact Thermal MEMS sensor array This repository provides sample projects for integrating OMRON D6T MEMS Thermal Sensors with the evaluation kits 2JCIE-EV01-AR1, ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

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 ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...
