The parts arrived for the RPM meter that uses an Arduino and reciprocal counting to get a three-times-a-second update rate with 1rpm resolution.

On one range, the Arduino charges the capacitor through one resistor and discharges it through another while timing the operation. The amount of time taken corresponds to the capacitance.

If you are interested in creating an Arduino wind speed meter or anemometer to monitor the wind strength in your location, you might be interested in this quick tutorial I have put together to ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Arduino enthusiasts and makers looking for a project to keep them busy this weekend may be interested in a new Arduino powered DIY Gauss meter that once constructed can easily provide feedback on ...

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.

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 ...

Arduino has announced the availability of a design starter kit for the Genuino Uno embedded computing module. And if you want to design a LOVE-O-METER to measure how hot-blooded you are or a LIGHT ...
