1．设计一个十字路口的交通灯控制电路，要求甲车道和乙车道两条交叉道路上的车辆交替运行，每次通行时间都设为25秒； 2．要求黄灯先亮5秒，才能变换运行车道； 3.根据交通灯控制系统框图，画出完整的电路图。 3.设计出PCB图 -1. Design a crossroads, the traffic lights control circuit, A request lane motorway and two B crossover vehicles on the road alter

一个交通灯的微机设计实验。包括实验链路图源代码 还有解析说明 -a traffic light computer to design experiments. Chains including experimental map source code analysis also shows
