SD card datalogger
This example shows how to log data from three analog sensors
to an SD card mounted on the Linux using the Bridge library.
to an SD card mounted on the Arduino Yun using the Bridge library.
The circuit:
* analog sensors on analog ins 0, 1, and 2
* SD card attached to SD card slot of the Arduino Yun
You can remove the SD card while the Linux and the
sketch are running but becareful to don't remove it while
the system is writing on it.
sketch are running but be careful not to remove it while
the system is writing to it.
