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 ...

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 ...

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 ...

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. Arduinos ...

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.

And you get a clock at the end of it! [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.

Learn how to build a DIY current and voltage meter using Arduino Nano. This project demonstrates step-by-step instructions to measure current, voltage, and wattage with precision. Using simple ...

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 ...
