基于Arduino的液晶声光万年历的设计与实现

The Design of the Liquid Crystal Acousto-optic Calendar Based on Arduino

针对Arduino平台日益广泛的应用,设计了液晶声光万年历系统。系统采用Arduino UNO R3作为主控板,采用1602液晶屏模块作为数值显示部分,采用DS3231模块提供时间、日期和温度数据,采用蜂鸣器和RGB LED发光管为闹钟和整点提示发出声光信号。通过系统软硬件功能验证和性能测试,设计的液晶声光万年历具备了时间、日期、星期和温度显示,以及声光闹钟和整点提示等实用功能,每周计时误差小于1秒。系统可以作为Arduino教学的典型项目应用于教学实践,也可以作为一个具有实用性的计时产品投入使用。

With the widespread application of Arduino platform, LCD acousto-optic calendar system are designed. The Arduino UNO R3 are used as the main control board. 1602 LCD module are adopted as a numerical display section. DS3231 modules provide time, date and temperature data, while buzzer and RGB LED tube for the alarm clock and tip acousto-optic signal sent by the hour. Through the system hardware and software function verification and performance test, the design of liquid crystal light calendar with the time, date, week and temperature display, and practical function such as sound and light alarm, and prompt the hour a week timing error is less than 1 second. System can be used as a typical project Arduino teaching in teaching practice, also can be used as a practical timing products.
