- SD card datalogger
-
- This example shows how to log data from three analog sensors
- to an SD card using the SD library.
-
- The circuit:
- * analog sensors on analog ins 0, 1, and 2
- * SD card attached to SPI bus as follows:
- ** MOSI - pin 11
- ** MISO - pin 12
- ** CLK - pin 13
- ** CS - pin 4
-
- created 24 Nov 2010
- modified 9 Apr 2012
- by Tom Igoe
-
- This example code is in the public domain.

-// functions will not work.
