SPI MicroSD Card Adapter v0.9b for Arduino

CATALEX SD Card Shield Expansion Board - Blue + Black
(Works with Official Arduino Boards and Examples)

Arduino Examples: SD card datalogger:

Example from Arduino examples shows how to log data from three onboard analog sensors to an SD card using the SD library. 

The circuit:

### SD card attached to SPI bus as follows:

**  GND: Ground

**  VCC: 5v 

**  MOSI - pin 11

**  MISO - pin 12

**  CLK - pin 13

**  CS - pin 4

The log looks like this:

427,407,387
385,385,376
379,377,374
370,370,366
...

287,288,283
283,284,277
290,291,286
302,301,299
303,300,297

Comma delimited Data was then opened in Libre Office and graph exported to Jpg.
