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.

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 ...

Conversely, the comparator output and the connection to the Arduino’s analog converter (A0) are labeled nodes from the “Output and Labels” menu. The names are significant, including the spaces.

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 ...
