交通灯（加数码管），控制南北灯和东西灯，在数码管有显示，没有加电路图，想要的联系我（因为只是能在电脑上看到效果，与实际上的肯定有差距），使用51单片机，keil开发环境，电路图用的protues，说明这么多够了吧。。。。只是一个简单练习题而已-Traffic lights (add digital control), control of north-south and east-west light lights, in the digital control has shown that there is no add circuit, the desired contact me (because it is only able to see on computer effects, and there is in fact an affirmation of the gap), the use of 51 single-chip, keil development environment, circuit diagrams used protues, that so many have had enough now. . . . Just a simple Exercises only
