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.

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 ...

If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. Hackaday Alum [Phil Burgess] developed the device using an RGB LED m… ...

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 ...

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 ...

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 ...

This one caught my eye on twitter, the Arduino Audio Meter - an Arduino-based device described as spectrum analyser and guitar pedal in one... It's based on the Uno board, to be precise, fitting ...
