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
