  SD card file dump

 This example shows how to read a file from the SD card using the

 SD library and send it over the serial port.

 The circuit:

 * SD card attached to SPI bus as follows:

 ** MOSI - pin 11

 ** MISO - pin 12

 ** CLK - pin 13

 ** CS - pin 17 (listed on Micro as SS)

#include <SPI.h>

//On the Arduino Micro, the SS pin is defined in software as pin 17. 

const int chipSelect = 17;

void setup()

{

 // Open serial communications and wait for port to open:

  Serial.begin(9600);

  delay(1000); //this 1 second delay isn't strictly speaking necessary, but it seems to smooth over the USB serial monitor a bit. 

   while (!Serial) {

    ; // wait for serial port to connect. Needed for Leonardo only

  }

  Serial.print("Initializing SD card...");

  pinMode(17, OUTPUT); //set SS pin as output. 

  // see if the card is present and can be initialized:

  if (!SD.begin(chipSelect)) {

    Serial.println("Card failed, or not present");

    // don't do anything more:

    return;

  }

  Serial.println("card initialized.");

  // open the file. note that only one file can be open at a time,

  // so you have to close this one before opening another.

  File dataFile = SD.open("datalog.txt");

  // if the file is available, write to it:

  if (dataFile) {

    while (dataFile.available()) {

      Serial.write(dataFile.read());

    }

    dataFile.close();

  }  

  // if the file isn't open, pop up an error:

  else {

    Serial.println("error opening datalog.txt");
