//There is a library for this IC, you can get it from https://github.com/avishorp/TM1637 , as usual there is a built in example but here is a simple sketch 

#include <TM1637Display.h>

const int CLK = A13; //Set the CLK pin connection to the display
const int DIO = A12; //Set the DIO pin connection to the display

int numCounter = 0;

TM1637Display display(CLK, DIO); //set up the 4-Digit Display.

void setup()
{
display.setBrightness(0x0a); //set the diplay to maximum brightness
}

void loop()
{
for(numCounter = 0; numCounter < 1000; numCounter++) //Iterate numCounter
{
display.showNumberDec(numCounter); //Display the numCounter value;
delay(1000);
}
}
