这个交通灯控制电路，结合了现在实际的道路情况而开发的，并非简单的交通灯控制系统，里面包括数码管指示显示和红绿灯指示，要求在红绿灯指示的情况下，还要示数码管进行倒计时。可以说，非常不错，我花了几个晚上调试出来的。值得大家学习和参考-The traffic light control circuit, combined with the actual road conditions is developed, not a simple traffic light control system, which includes direct digital display and traffic lights, requiring the case of traffic lights, but also the countdown LED display . It can be said, very good, I spent a few nights out of debugging. Worth learning and reference
