CLOCK 7SEG sử dụng ATMEGA16

+ File full code và mô phỏng ở cuồi bài.Lưu ý, mô phỏng dùng Proteus 8.5

- Sử dụng 3 phím SETTING, UP, DOWN để điều chỉnh giờ.

               + Nhấn SETTING lần thứ nhất để chỉnh giờ, lần 2 để chỉnh phút. dùng phím UP, DOWN để di chuyển giữa 2 đơn vị GIỜ và PHÚT.

CHÚ Ý: Khi nhấn SETTING hay di chuyển giữa các đơn vị bằng UP or DOWN các bạn sẽ ko thấy các đơn vị nhấp nháy ( mình chưa sửa phần này), vì thế các bạn lưu ý nhớ số lần nhấn nút.
