If you fancy building your very own DIY magnetometer you may be interested in a Arduino project published to the Instructables website by maker Markus Opitz. His magnetometer costs less than €50 ...

you could get a magnetometer app for your phone to test out the strength of your Buckyballs, but this is more fun, and you can use it in more places. This build doesn’t take much — an Arduino ...

The build uses a HMC5883L magnetometer. While this can detect ... The output of the device is read by an Arduino Nano, which is hooked up to a string of WS2812B LEDs and a small OLED display.

and a magnetometer. Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using the 5 volts out available on the Arduino Uno.

Adafruit explains a little more about the Triple-axis Magnetometer ... this little wonder with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/ Metro328) logic levels. Additionally, since it speaks ...

An innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics has been developed by scientists.
