单片机模拟交通灯显示。其中，红灯与绿灯显示时间均为50s，中间的黄灯显示时间为15s。绿灯用八位发光二极管流动闪烁作代表；红灯用八位发光二极管全亮作代表；黄灯用八位发光二极管全亮全灭闪烁作代表。刚开始显示的为绿灯。(SCM simulated traffic light display. Among them, the red and green display times are 50s, in the middle of the yellow light is displayed for 15s. Green with eight light-emitting diode flashes as a representative flow red with eight full brightness light-emitting diodes as a representative yellow with eight light-emitting diodes for all light flashes Quanmie representatives. Just beginning to show as green. Display order: green- yellow- red- yellow- green- yellow- red- ..................)
