Arduino: Put Data in Other File The below code starts off with lots of data in the beginning, distracting the reader from the actual code.  What is the best practice to clean this up:

#include &lt;Wire.h&gt;
// For LED Backpack
#include "Adafruit_LEDBackpack.h"
#include "Adafruit_GFX.h"
// For LCD Shield
#include &lt;Adafruit_MCP23017.h&gt;
#include &lt;Adafruit_RGBLCDShield.h&gt;

// For pixel Units, such as hero
#include &lt;Unit.h&gt;


Adafruit_BicolorMatrix matrix = Adafruit_BicolorMatrix();
Adafruit_RGBLCDShield lcd = Adafruit_RGBLCDShield();

Unit *hero;
boolean doesNeedRedraw = true;
boolean textNeedsRedraw = true;
int8_t lastButtonPress = 0;
int8_t frame = 0;

void setup() {
  /* Important Setup Routine */
}

static const uint8_t PROGMEM
  smile_bmp[] =
  { B00111100,
    B01000010,
    B10100101,
    B10000001,
    B10100101,
    B10011001,
    B01000010,
    B00111100 },
  neutral_bmp[] =
  { B00111100,
    B01000010,
    B10100101,
    B10000001,
    B10111101,
    B10000001,
    B01000010,
    B00111100 },
  frown_bmp[] =
  { B00111100,
    B01000010,
    B10100101,
    B10000001,
    B10011001,
    B10100101,
    B01000010,
    B00111100 },
  walls_bmp[] =
  { B10100000,
    B10110000,
    B10010000,
    B11011100,
    B01000100,
    B01110100,
    B00010100,
    B00011100 };

void loop() {
  /* Important Main Loop Routine */
}
One way to clean that up is to create a "Globals.inc" file and cut and paste all of your globals into there.  After that's done, simply include the globals file from your main .ino file with #include "Globals.inc"

(Main.ino)

#include &lt;Wire.h&gt;
// For LED Backpack
#include "Adafruit_LEDBackpack.h"
#include "Adafruit_GFX.h"
// For LCD Shield
#include &lt;Adafruit_MCP23017.h&gt;
#include &lt;Adafruit_RGBLCDShield.h&gt;

// For pixel Units, such as hero
#include &lt;Unit.h&gt;

#include "Globals.inc"

void setup() {
  /* Important Setup Routine */
}

void loop() {
  /* Important Main Loop Routine */
}


(Globals.inc)

Adafruit_BicolorMatrix matrix = Adafruit_BicolorMatrix();
Adafruit_RGBLCDShield lcd = Adafruit_RGBLCDShield();

Unit *hero;
boolean doesNeedRedraw = true;
boolean textNeedsRedraw = true;
int8_t lastButtonPress = 0;
// 0-255
uint8_t frame = 0;

static const uint8_t PROGMEM
  smile_bmp[] =
  { B00111100,
    B01000010,
    B10100101,
    B10000001,
    B10100101,
    B10011001,
    B01000010,
    B00111100 },
  neutral_bmp[] =
  { B00111100,
    B01000010,
    B10100101,
    B10000001,
    B10111101,

    B01000010,
    B00111100 },
  frown_bmp[] =

    B01000010,
    B10100101,
    B10000001,
    B10011001,
    B10100101,
