多功能数字钟设计报告多功能数字钟设计报告 摘 要 本设计采纳一块单片机(AT89S52)作为多功能数字钟的控制核心,加以温度传感器、红外接收管、蜂鸣器、液晶显示器(LCD1602)、电源电路及其他电路构成
实现了时间设置、闹铃设置、闹铃开和关的功能;LCD 显示小时、分钟,有 AM、PM 指示灯,闹钟就绪灯,闹钟到点蜂鸣器报警,220V 供电基本功能
另外,本设计还实现了通过切换键盘显示现场温度,红外停止闹铃的功能
Abstract This design uses a single chip (AT89S52) as the core controller of a multi-functional digital clock,complemented by temperature sensor,infrared receiver,buzzer,liquid crystal display(LCD1602),power circuit and other circuit
It implementes time setting,alarm setting,and alarm on/off functions
Moreover, it has some basic functions such as displaying hour and minute,AM/PM indicator light,alarm clock ready light,buzzer alarm and 220V power supply
In the end,this design also can show the scene temperature through switching the keyboards,and stop the alarm by infrared circuit
