1) 以单片机为核心部件组成一个音乐播放器。
2) 利用单片机的定时器产生乐谱的各种频率方波,信号经过放大后由喇叭发出声音。
3) 自行定义按键盘,每按一键,可选择一首歌曲进行演奏,某段音乐令单片机连续播放,演奏可通过按键来中断。
4) 在LCD上显示演奏歌曲的名称。
-1) the composition of the core components of SCM as a music player. 2) the use of MCU timer generated scores of the various frequency square wave signal through the amplified sound from the speakers. 3) self-defined keyboard, every click of a button, select a song to play, a certain period of continuous playback of music in SCM, playing by pressing a button to interrupt. 4) In the LCD displays the name of the song playing.

六位电子密码锁
采用89s52(51,52都可),4*4键盘,六个数码管,74ls04(位选),573(8D锁存器)。
说明:P2---数据(接573)―――(接数码管)
P1---位选 ---(按74ls04)
P0--4*4键盘
密码一次性设置(编程时写入的)
电路简单,此源程序仅供初学者学习,可自行扩展密码模块(加24C02)。
编绎软件为wave

随着精准农业的发展,农业种植和农业研究人员需要一种手持式NDVI测量仪,以便对农作物长势进行定量测量。本文讨论了一种手持式NDVI测量仪的完整设计过程,详细论述了设计原理,并给出了详尽的单片机程序、设计电路原理图及PCB图。该NDVI测量仪采用太阳光作为光源,光电探测器采用滤光片和光敏二极管实现,用AT89C51单片机控制。其具有结构简单、成本低、轻便、低功耗的特点。-With the development of precision agriculture and farming, and agricultural researchers need a handheld NDVI measuring instrument, in order to crop growth for quantitative measurement. This paper discusses a handheld meter NDVI the integrity of the design process, discussed in detail the design principles, and gives a detailed SCM procedures, circuit schematics and PCB plans. The NDVI measuring instrument used sunlight as a light source, photodetector using filters and photodiode realized, with AT89C51 control. Its structure is simple, low cost, lightweight, low-power characteristics.
