I am trying to make a digital clock (24:00 type), where each number is individual image, that should change. So, i am want to change sprites for multiple image in one code, but when i initializing two image, the second one is just ignore. And plus when i am attach this code to the object it work on that object, not on image, that i am pointing at. How can i fix that?

using UnityEngine;

using System.Collections;

using UnityEngine.UI;

public class Timer : MonoBehaviour

{

[Header("Sprites for times")]

public Sprite _One;

public Sprite _Two;

public Sprite _Three;

public Sprite _Four;

public Sprite _Five;

public Sprite _Six;

public Sprite _Seven;

public Sprite _Eight;

public Sprite _Nine;

public Sprite _Zero;

public GameObject BACK;
public Image _seconds;
public Image _minuts;

private bool secy = true;
private bool miny = true;
private void Start()
{
    BACK = GetComponent<GameObject>();
    _seconds = GetComponent<Image>();
    _seconds.sprite = _Zero;
    _minuts = GetComponent<Image>();
    _minuts.sprite = _Zero;
}

void FixedUpdate()
{
    StartCoroutine(_AloneMinut());
    StartCoroutine(_Decade());
}

private bool JustWhait_sec()
{
    return secy;
}

private bool JustWhait_min()
{
    return miny;
}
private IEnumerator _AloneMinut()
{
    yield return new WaitUntil(JustWhait_sec);
    secy = false;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _One;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Two;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Three;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Four;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Five;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Six;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Seven;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Eight;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Nine;
    yield return new WaitForSeconds(2);
    _seconds.sprite = _Zero;
    secy = true;
}

private IEnumerator _Decade()
{
    yield return new WaitUntil(JustWhait_min);
    miny = false;
    yield return new WaitForSeconds(20);
    _minuts.sprite = _One;

    yield return new WaitForSeconds(20);
    _minuts.sprite = _Zero;
    miny = true;
}
