光控電機驅動電路的PCB圖[圖片]
ATMEL公司的AT89S52單片機,是低功耗、高性能CMOS 8位微處理器，具有8K在系統(tǒng)可編程Flash存儲器。使用Atmel公司高密度非易失性存儲器技術制造，與工業(yè)80C51產(chǎn)品指令和引腳完全兼容。片上的Flash允許程序存儲器在系統(tǒng)編程，亦適于常規(guī)編程器。在單芯片上，擁有靈活的8位CPU和在系統(tǒng)可編程Flash，使得AT89S52為眾多嵌入式控制應用系統(tǒng)提供高靈活，超有效地解決方案。
AT89S52具有以下標準功能：8K字節(jié)Flash，256字節(jié)RAM,32位I/O接口，看門狗定時器,2個數(shù)據(jù)指針，三個16位定時器/計數(shù)器，一個6向量2級中斷結構，全雙工串行口，片內(nèi)晶振及時鐘電路。另外，AT89S52可降至0Hz靜態(tài)邏輯操作，支持2種軟件可選擇節(jié)電模式?？臻e模式下，CPU停止工作，允許RAM、定時器/計數(shù)器、串口、中斷繼續(xù)工作。掉電保護方式下，RAM數(shù)據(jù)被保存，振蕩器被凍結，單片機一切工作停止，直到下一個中斷或硬件復位為止。
由于單片機的種類很多，在選擇單片機時要依據(jù)實際設計要求選擇合適的單片機。在本課題中，選用的是ATMEL公司的AT89S52。

仿真調(diào)試[圖片]1）查找所需要的元器件 通過相關關鍵字選取元器件或通過索引系統(tǒng)查找元器件，放置元器件，編輯器件，填加“地”和“電源”。（2）根據(jù)電路圖進行連線 將鼠標移到要連接導線的起點處，此時光標中心出現(xiàn)一個“×”，在此處單擊左鍵，導線的起點固定下來，再將鼠標鼠標一到下一個連接處，光標中心出現(xiàn)一個“×”， 再單擊，導線止點再次出固定下來。若連線需要拐彎，就在拐彎處單擊左鍵即可。（3）下載所寫完的C語言程序即可以仿真 雙擊AT89S52，在編輯里面Program File加載Keil軟件生成的“光控電機.hex”文件，然后點擊“OK”確認。
加熱門了~！
樓主一直從事單片機數(shù)控電源方面的嘛？~

With the rapid development of science and technology, "Information Age" to come, as a means of access to information - sensor technology has been significant progress, more and more extensive areas of its application, its becoming more demanding, more urgent needs . Sensor technology has become the measure of a country's level of development of science and technology an important landmark. Therefore, to understand and master the basic structure of various types of sensors, the working principle and characteristics are very important. In order to improve awareness and understanding of the sensor, especially for the light sensors in-depth research and its use and purpose, based on practical, extensive, and the principle of the typical design of the system. In this thesis, combining light sensors microchip technology development and design of this light control system, curtains or other equipment if the installation of the sensor, the sensor automation control. The AT89S52 microcontroller and photoresistor light control as the core design of the motor drive circuit can realize automation of light control is a simple structure, stable performance, easy to use, inexpensive, intelligent light-sensitive circuit, has some practical value.
