利用动态扫描和定时器1在数码管上显示出从765432开始以1/10秒的速度往下递减直至765398并保持显示此数，与此同时利用定时器0以500MS速度进行流水灯从上至下移动，当数码管上数减到停止时，实验板上流水灯也停止然后全部开始闪烁，3秒后（用T0定时）流水灯全部关闭、数码管上显示出“HELLO”。到此保持住。

-Dynamic scan and Timer 1 in the digital pipe shows start from 765 432 to 1/10 sec down and keep decreasing until the show this number 765,398, while the use of Timer 0 to 500MS speed of light from the water to Under the move, when the digital pipe to reduce it to stop when the lights stopped flow experiments on-board and then all the flashes, 3 seconds (with the T0 timer) running water all the lights off, the digital control on the show " HELLO" . This to keep living.
