mình mới sửa lại link rồi bạn ! Mạch này mình mới chỉ cho chạy mô phỏng, mình chưa làm mạch thực tế ! Bạn nào làm thì lưu ý phần delay hiển thị, hiện tại mình để 50, mình delay để trên prteus chạy được, lưu ý thêm giá trị ở hàm while() trong mỗi hàm if của phần hiển thị. Hai cái này : 1 cái để chỉnh lúc led bị nháy, 1 cái để chỉnh độ sáng của led.Last edited by tramng; 24-02-2014, 17:07.Comment
