Sounds like you've been told what components you have to use, so the battle is already half over.

Look at the data sheets and figure out what each chip does, what's its function? How does that function relate to making a clock?

You’ve been given a homework assignment without instruction about the content of the assignment? Did your instructor really not explain anything about this before assigning it?

OK, but she didn’t explain anything about the operation of the ICs or how they work together? She just gave you the assignment and sent you off to find someone else to explain it?

Sounds like you used unauthorized resources and the only thing you demonstrated was that you could build something that someone else designed and that you tried to take credit for. Seems like you're trying to do the same thing again.

This is YOUR homework. YOU need to be the driving force behind solving it. We are more than willing to help guide you, but we won't spoon feed you a solution so that you can get credit you don't deserve. That does you no good at all.

So in other words, you copied a circuit and didn't learn a thing? Imagine that.

A 7490 is a type of counter. Guess what? A 7493 is also a type of counter that works a little differently. What's a clock? A counter of seconds, at least the first stage.

this is my country's language is vietnamese and if you are interested, translate it into english, you will better understand my situation
Môn tôi đnag học là kỹ thuật xung số, có 2 giáo viên dạy tôi thầy ấy chỉ dạy phần lý thuyết phần xung và phần số chỉ dạy tôi về led 7 đoạn và thầy đã kết thúc phần dạy lý thuyết ở đó. Sau đó cô giáo hiện tại dạy tôi cô ấy chỉ giao bài tập cho chúng tôi thực hành và chúng tôi không biết gì về các ic chỉ ra bài tập và chúng tôi không hiểu gì, chúng tôi có hỏi cô thì cô chỉ bảo lâu qua cô quên rồi hay cho các bài tập trong sách và làm nó khó hơn bằng cách thay đổi các dữ liệu có trong bài tập nhưng chúng tôi không thể làm gì được. Đây là tình cảnh hiện tại của lớp tôi mong bạn hiểu cho

hi D,
This is the English translation:
Moderation.

The subject I am studying is digital pulse technology, there are 2 teachers who taught me he only taught the theory part of pulses and the number part taught me about 7-segment led and he ended the theory part there. Then the current teacher taught me she just gave us the exercises to practice and we didn't know anything about the ic indicating the exercise and we didn't understand anything, we asked her, she just told me a long time ago she forgot or gave the exercises in the book and made it more difficult by changing the data contained in the exercises but there was nothing we could do. This is the current situation of the class I hope you understand
