It is extremely frustrating when people do not Read this before posting a programming question and follow the instructions

Here is your sketch Auto formatted in the IDE and posted in code tags as recommended

#include <TM1637Display.h>

// TM1637 Module connection pins (Digital Pins)
#define CLK 5
#define DIO 6
TM1637Display display(CLK, DIO);

int bt = 3;
int led = 13;
int state = 0;

const uint8_t SEG_DONE[] =
{
  SEG_B | SEG_C | SEG_D | SEG_E | SEG_G,           // d
  SEG_A | SEG_B | SEG_C | SEG_D | SEG_E | SEG_F,   // O
  SEG_C | SEG_E | SEG_G,                           // n
  SEG_A | SEG_D | SEG_E | SEG_F | SEG_G            // E
};

// time calc
#define numberOfSeconds(_time_) ((_time_ / 1000) % 60)
#define numberOfMinutes(_time_) ((_time_ / 1000) / 60)
// hold time selected in ms.

unsigned long timeLimit = 600000;// 1000*60*1 = 10mins

void setup()
{
  pinMode(led, OUTPUT);
  pinMode(bt, INPUT);
  // Setup serial
  Serial.begin(115200);
  delay(50);
  Serial.println("-----------Timer Arduino Comms up------------");
  //display setup
  display.setBrightness(4);    // LED 밝기조정   0~6
  //display.setBrightness(0x0c);
  display.showNumberDecEx(0, 0x40, true);    //64
}


void loop()
{
  int value = digitalRead(bt);
  if (value == LOW)
  {
    if (state == 0)
    {
      state = 1;
    }
    else if (state == 1)
    {
      state = 0;
    }
    delay(500);
  }
  if (state == 0)
  {
    digitalWrite(led, LOW);
  }
  else if (state == 1)
  {
    digitalWrite(led, HIGH);
  }
  for (long i = timeLimit; i > 0; i = i - 1000) // data type = long
  {
    // To display the countdown in mm:ss format, separate the parts
    int seconds = numberOfSeconds(i);
    int minutes = numberOfMinutes(i);
    Serial.println(i);
    // This displays the seconds in the last two places
    display.showNumberDecEx(seconds, 0, true, 2, 2) ;
    // Display the minutes in the first two places, with colon
    display.showNumberDecEx(minutes, (0x80 >> 1), true, 2, 0) ;  // turn on colon    원본은  0x80 >> 3 인데 콜론이 on 되지 않아 0x80 >> 1 로 변경
    delay(1000);
  }
  display.setSegments(SEG_DONE);
  delay(2000);
  timeLimit = 0;
}

Now, would you care to describe what should happen and what does happen when you run it as “does not work” is not enough to go on

Hi,Here is a page showing how to work on combining sketches:

It would be helpful if you state what "does not work" means. Better yet state what "works" means.
