模拟交通灯，并带有数字显示的程序。初始时全为红灯，显示“HELLO”字样。然后交通灯以“红绿、红黄、绿红、黄红”四种状态做循环，而且黄灯会闪烁，每种状态都带有到数记时。当按下P3_2时，变成“红红”状态，并显示“STOP”字样！ -simulated traffic lights and figures with the procedure. When all of the initial red, shows that the "hello" words. Then traffic lights to the "black, red and yellow, green, red, yellow red" state to do four cycle, but the yellow light flashes, each state will have a few to remember when.
