随着居民生活水平的不断提高，自行车不再仅仅是普通的运输、代步的工具，而是成为人们娱乐、休闲、锻炼的首选。这就为自行车的速度里程表的诞生提供了条件,一款经济实惠的速度里程表能够在满足人们最基本的需求下，更好地帮助人们清楚地知道当前的速度、里程等物理量,更好的掌握当前运动状况。
本论文主要阐述一种具有警报功能的自行车的里程表的设计。以AT89C52单片机为核心，A44E霍尔传感器测转数，实现对自行车里程/速度的测量统计，采用24C02实现在系统掉电的时候保存里程信息，并能将自行车的里程数及速度用LED实时显示。
With the continuous improvement of the living standard of the residents, the bicycle is no longer only a common transportation and step tool, but the first choice for people's entertainment, leisure and exercise. This provides the conditions for the birth of a bicycle speedometer. An economical speedometer can better help people know the current speed, mileage and other physical quantities, and better grasp the current sports conditions, to meet the basic needs of the people.
This paper mainly describes the design of a bicycle odometer with alarm function. Taking the AT89C52 single chip as the core, the A44E Holzer sensor measured the rotation number, realized the measurement and statistics of the bicycle mileage / speed, and used 24C02 to save the mileage information when the system dropped the power, and could display the mileage and speed of the bicycle in real time with the LED.

熙熙攘攘的街头，人流车水有条不紊地行进着，靠的是交通灯的指挥作用，交通灯的绿、红、黄灯交替工作着，指挥着交通，维持着秩序。
课程设计采用单片机AT89C51为中心器件来设计交通灯，从而模拟十字路口交通灯的各种状态显示。设计由单片机AT89C51，LED八位数码显示管等组成。软件上采用C语言编程实现。主要编写了主程序，数码管显示程序和延时程序，经模拟，实现交通灯的功能。操作简单，设计简单易懂，但由于采用的是纯延时，因此会有一定的误差，但不影响总体效果。
在遇紧急情况时，可通过按键控制交通灯全亮红灯，从而解决紧急情况的交通问题。
Bustling streets, traffic cars, water methodically moving, relying on the command of the traffic lights, traffic lights green, red and yellow lights alternating work, directing traffic, maintaining order.
The curriculum design uses the single chip microcomputer AT89C51 as the central device to design the traffic lights, thus simulates each kind of status display of the intersection traffic lights. Design by SCM, AT89C51, LED, eight bit digital display tube and so on. The software is programmed with C language. Mainly written in the main program, digital display procedures and delay procedures, by simulation, to achieve traffic lights function. The operation is simple, the design is simple and easy to understand, but because of the adoption of pure delay, there will be some errors, but it does not affect the overall effect.
In case of emergency, the traffic lights can be controlled by a button to complete the red light, thus solving the traffic problems in an emergency. (2017-08-04, C51, 54KB, 下载2次)

随着科技的不断发展，社会的不断进步，供人们娱乐休闲的工具越来越多，摇摇棒也随之成为一个热点产品。“摇摇棒”是基于人眼视觉暂留原理而产生的,当进行摇动时，由于人的视觉暂留会在发光二极管摇动区域产生一个视觉平面，从而达到在该视觉平面上传达信息的作用。本文介绍了以STC11F02E单片机控制为主控芯片、配合高亮度LED二极管以及水银开关构成简易摇摇棒的设计过程，通过分时刷新32个发光二极管来显示输出文字或图案等信息。
As we all know, the human eye visual persistence phenomenon, because the eye is unresponsive, it enriched the human visual perception.
With the continuous development of science and technology, social progress, offer people entertainment tool more and more, shaking his stick also becomes a hot product. Swing is based on the human visual persistence principle which, when moved, due to the persistence of vision in the light emitting diode shake the region produces a visual plane, in order to achieve the vision plane to convey information about the role of. This paper introduces theSTC11F02Esingle chip microcomputer as main control chip, with high brightness LED diode and a mercury switch . A simple rocking rod design process, through time-sharing refresh 16 light-emitting diodes to display the output of text or graphics information. (2016-05-27, C51, 24KB, 下载3次)
