Code Led Sao Băng Trái Tim 32 Led+ Chip 8051 Chi Tiết Nhất

Mình nhìn thấy mấy video led sao băng trên Youtube chạy nhìn đẹp....có 1 code led sao băng 3 màu của bạn daohuytien ben DTVN nhưng chỉ có 24 led. Mình ngồi hì hục viết lên 32 led được 5 hiệu ứng mà đã Full hơn 7k rồi..toàn setbit tốn bộ nhớ dã man...Bạn nào thích thì làm chơi cho vui.
