Hall Effect Sensor - Data Log

Hi,

Extremely new to Arduino based projects, however been tasked to develop a small project that will changes in magnetic field strength.

Able to replicate some of the circuits online. Having trouble dumping the data, which is being detected by the hall effect sensors that are being used.

using the above circuit but alongside the LED, I would like the field strength detected to be dumped in an SD card.

Thanks in advance

Do you have the SD card and module yet?

Check out Adafruit Assembled Data Logging shield for Arduino : ID 1141 : $13.95 : Adafruit Industries, Unique & fun DIY electronics and kits for ideas and a tutorial.

the sensor mentioned here : "Arduino Hall Effect Sensor Tutorial with Code and Schematic Diagram"

.. is a digital one. It can determine if a magnetic field is present or not.
What do you want to log on a card?
