+  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.
