This topic uses the single chip mic

This topic uses the single chip microcomputer control technology, the whole system is reduced to a small single chip microcomputer, improve the portability and economy of traffic lights. The design includes hardware circuit design and program design. Hardware circuit module mainly includes single chip microcomputer, light emitting diode composed of analog traffic lights, reset circuit, alarm circuit, oscillation circuit, display digital tube module. In the process of single chip microcomputer development of traffic signal lamp, in addition to the necessary hardware design, it is also inseparable from software programming. This design uses keil to program. Compared with hardware design, software programming is more complex, and a series of problems such as time display, signal lamp control, emergency switch, buzzer alarm should be taken into account. At the same time also have a certain C language programming foundation and certain logical thinking ability.
