Arduino Projects: Arduino Datalogger with Memory Card by T.K. Hareendran

Robometricschool. - This is one Arduino Project for you who want to update your knowledge to Arduino Application in this time. This information titled with Arduino Datalogger with Memory Card that written by T.K. Hareendran.

How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task. Below is a simple tutorial on how to capture data generated from your Arduino and write it to a text file on a microSD card for later analysis. Let’s get started!

SD Card Breackout Board

All connections (pins) in the breakout board are clearly labeled. Take note — the breakout board uses SPI protocol, so for use with Arduino Uno or a Pro Mini-compatible board, make interconnections as follows:

5 V to 5 V (VCC)
GND to GND
D13 to SCK
D12 to MISO
D11 to MOSI
D10 to CS

Another Arduino Library

Now get ready to install the required Arduino library. Just download the zip file “SdFat-master” from here, extract the zip file, and copy the “SdFat” folder into your Arduino IDE’s “Libraries” folder. Location of the library — usually in the “Sketchbook” folder — can be found in the Arduino IDE’s “Preferences” menu. As you may have noticed, there is an SD card library included with the Arduino IDE. However, we prefer the above-introduced library.
