    Since this a homework, so the members won't give you the direct answer, you have two parts in your questions, and need to mix them to working together, what you think of or design or searching so far?

    So what do you believe YOUR role is in completing YOUR homework? Just turning in the schematics that someone else made for you and taking credit for it?

    YOU need to show YOUR best efforts to solve YOUR homework.

    you could use a 555 timer in astable mode, set the delays with presets to get the desired times.
