With the increasing development of the microcontroller, its applications are increasingly being used by "auto light control system" design, the microcontroller can be consolidated and expanded knowledge. In the living environment, automatic control requirements will have a part of the control of the microcontroller; from simple to complex, who can imagine the place is almost always use the microcontroller needs. SCM applications conducive to miniaturization, versatile and intelligent, able to improve labor efficiency, reduce labor intensity, improve product quality, improve the working environment.
SCM applications in automotive electronics is very wide, such as automobile engine controllers, automobile engine based on CAN bus intelligent electronic controller, GPS navigation system, abs anti-lock system, brake system, tire pressure detection. SCM in industrial, commercial, financial, scientific research, education, electricity, LED headlamp used in various automotive lighting has become a research and development institutions working to develop goals, is one of the major developments in the future direction of the automotive lighting sector.
This course is to design a microcomputer control system, the car carried a left turn, right turn, beam lights, high beam, brake, when combined emergency (alarm) switching and other operations, to achieve control of the various signal lights. This design is a single-chip parallel input / output port circuit applications, the I / O port control of light-emitting diode off, flicker, plus some key circuit reset circuit crystal module, light module to simulate automobile taillights function.
