How do i combine two Arduino sketches?

Projects Programming

This is my chronometer sketch with 7 segment display and i want to use a button in it as switch(on/off)

code 1 is my chronometer sketch (working)

void setup(){
  pinMode(0,OUTPUT);
  pinMode(1,OUTPUT);
  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  pinMode(4,OUTPUT);
  pinMode(5,OUTPUT);
  pinMode(6,OUTPUT);
}
void loop(){
  int i;
  for( i = 0; i < 10; i++)
  {
    ShowNumber(i);
    delay(500);
  }
}
void ShowNumber(int number)
{
  switch(number)
  {
    case 0:
    digitalWrite(0,LOW);
    digitalWrite(1,LOW);
    digitalWrite(2,LOW);
    digitalWrite(3,LOW);
    digitalWrite(4,LOW);
    digitalWrite(5,LOW);
    digitalWrite(6,HIGH);
    break;
    case 1:
    digitalWrite(0,HIGH);
    digitalWrite(1,LOW);
    digitalWrite(2,LOW);
    digitalWrite(3,HIGH);
    digitalWrite(4,HIGH);
    digitalWrite(5,HIGH);

    digitalWrite(5,LOW);
    digitalWrite(6,LOW);
    break;
    case 7:

    digitalWrite(1,LOW);
    digitalWrite(2,LOW);
    digitalWrite(3,HIGH);
    digitalWrite(4,HIGH);
    digitalWrite(5,HIGH);
    digitalWrite(6,HIGH);
    break;
    case 8:
    digitalWrite(0,LOW);
    digitalWrite(1,LOW);
    digitalWrite(2,LOW);
    digitalWrite(3,LOW);
    digitalWrite(4,LOW);
    digitalWrite(5,LOW);

    digitalWrite(3,HIGH);
    digitalWrite(4,HIGH);
    digitalWrite(5,LOW);
    digitalWrite(6,LOW);
    break;
  }
}

code 2 is my switch sketch

/* 
 Debounce
 
 Each time the input pin goes from LOW to HIGH (e.g. because of a push-button
 press), the output pin is toggled from LOW to HIGH or HIGH to LOW.  There's
 a minimum delay between toggles to debounce the circuit (i.e. to ignore
 noise).  
 
 The circuit:
 * LED attached from pin 13 to ground
 * pushbutton attached from pin 2 to +5V
 * 10K resistor attached from pin 2 to ground
 
 * Note: On most Arduino boards, there is already an LED on the board
 connected to pin 13, so you don't need any extra components for this example.

// constants won't change. They're used here to

    // than the debounce delay, so accept the button state change:

and its not workin what i m missing here?

and its not workin what i m missing here?

It is working. It may not be producing the results that you want. But, since you haven't said what results it is producing or what results you want, all we can do is wish you luck.

So, good luck.

You may need to add a delay after say(i) so that each digit stays on the display long enough for you to read it. Other than that, what's it doing/not doing that doesn't meet your expectations?

Allright i did something first i add delay(500) after say(i), changed digital outputs under cases low to h?gh and if(basla == true) to if(basla ==false)
its now starting in off mode when i press the button it starts countin but second push is still not working.it must be turn off by second push. 1 push will start countin in 0 and 1 push will turn off 7 segment display
