西安科技大学高新学院 毕 业 设 计（论 文） 题 目 彩灯控制器电路设计 院（系、部) _______机电信息学院 _________ 专业及班级 ________电专1202班___________ 姓 名 _________ 张森____________ 指 导 教 师 ___________ 田晓萍_____________ 日 期 2015年5月28日  摘 要 With the development of microelectronics technology,improve people’s living standard,people on the surrounding environment,landscaping and lighting are not limited to monotonous incandescent lights have become a fashion trend.Lantern controller practical value in daily production practices in daily life have become increasingly prominent role.Carnival is also based on a variety of devices have emerged,the microcontroller because of its low price easy to use simple to control uour lights controlling the main device. More on the market with all the hardware circuit,the circuit structure is complex,single structure,once the finished products can only be a fixed pattern,not according to different occasions,adjust the brightness of different time periods,patterns and blinking frequency of the dynamic parameters,and some circuit the chip too much,circuit complexity,power consumption large,Liang Deng style monotonous lack of operation and other shortcomings,design a new type of lights can not wait. In recent years,the lantern for the landscaping,lighting the city has an important role should not be underestimated.So the city decorated with lanterns as the growing demand for technology and lanterns have become more sophisticated and synchronized.
