[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s … ...

Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum fr… ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

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, very ...

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 ...

And what's a geiger counter without ominous clicking? The Arduino microcontroller counts the pulses per minute. Using this measurement the microcontroller calculates Sieverts per hour.
