单片机交通灯模拟！交通灯的控制设计，所以要了解实际交通灯的变化情况和规律。假设一个十字路口为东西南北走向。初始状态 0 为东西红灯，南北红灯。然后 。过一段时间转状态 2 南北绿灯灭，黄灯闪烁几次，东转状态 1 东西红灯，南北绿灯通车，西仍然红灯。再转状态 3，东西绿灯通车，南北红灯。过一段时间转状态 4，东西绿灯灭，闪几次黄灯，南北仍然红灯。最后循环至状态 1。 -SCM traffic simulation. Traffic lights control design, so to understand the actual changes of the traffic lights and laws. Suppose a crossroads for the north and south, east and west. Initial condition 0 for a red light, the north and the south red light. Then. Turn over a period of time state 2, north and south green light, yellow light blink a few times, turn east state 1 thing a red light, the green light to traffic, the west is still red. To state 3, green light, being open to traffic between the north and the south red light. State 4 over a period of time, what a green light, flashing yellow light a few times, north and south is still red. The last cycle to state 1.
