dh.zipem đang làm đồng hồ led 7 thanh(thay led 7 thanh bằng cách ghép led đơn) em có gửi mạch và code mong các pro giúp.em mô phỏng trên proteus thì chạy.nhưng làm mạch thật thì chỗ quét led qua con 4511 không thấy gì cả.và cả nữa là con DS1307 em cho xuất ra chân 7 1hz mà dùng đồng hồ kiểm tra không thấy gì cả.em đã thay con DS1307 mới mà cũng không được.mong các pro giúp em
