使用keil平台与汇编编写的51单片机程序，可以执行电子时钟功能，可修改时间与设置闹钟，内含proteus仿真，验证通过。(The 51 microcontroller program written by keil platform and assembler can execute the function of electronic clock. It can modify the time and set the alarm clock, and contains proteus sim

使用STM32F0系列和OLED屏幕设计的手表程序，具有时钟日期显示，秒表，闹钟等功能(The watch program designed with STM32F0 series and OLED screen has functions of clock date display, stopwatch, alarm clock and so on.)

利用AVR单片机完成数字时钟设计，能够设定闹钟，通过按键来调整时间(Using the AVR microcontroller to complete the design of digital clock, the alarm can be set to adjust the time by key)

单片微型计算机简称单片机，又称为微控制器，是将CPU、RAM、ROM、定时/计数器、I/O接口电路集成到一块电路芯片上构成的微型计算机。本次设计的系统由单片机系统、数码管显示系统、键盘、蜂鸣器等组成，通过按键来控制单片机实现数字时钟的时、分、秒显示，12、24制转换，设定时间、闹钟等不同功能，并通过P0口的输出在LED上显示。(Single-chip microcomputers, also known as microcontrollers, are microcomputers that i
