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. It’s rather ...

The GPSDO used a push button and was read by an ADC on the Arduino Nano (Figure 3). This frequency counter design uses 2 pushbuttons that are connected to analog comparators to read their states.

[hamblin.joe] wanted to do a simple project for kids along these lines, so whipped up a neat design using analog meters to display the time. The build relies on that old stalwart, the Arduino Uno ...

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're ...

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

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 ...

developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign launched today for a new development board featuring 52 analog and ...
