基于AT89C52单片机的十字路口交通灯控制程序源代码和proteus仿真源文件，采用keil做开发环境-Based on AT89C52 crossroads traffic lights to control the program source code and proteus simulation source files, using keil to do development environment

出租车路程计价器，同时涵盖了proteus仿真和keil的编程，已经正常测试完毕，可以直接使用和功能上扩展，真的很好。-Taxi meter distance, while covering keil proteus simulation and programming, has been testing is completed properly, and can be used directly on extensions, really good.
