国外PLC设计的原理图和PCB(Principle foreign PLC design and PCB)

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)

DIYMP3，能智能播放，很好的运用了STM32系统相关知识，花费了我将近半年的努力，基本上包含了STM32所有功能的应用。(DIYMP3, play to intelligence, very good use of the STM32 system related knowledge, it took me about half effort, basically contains all STM32 function application.)

通过protues仿真实现的51单片机红外线遥控发射和接收解码装置。(Simulation achieve through protues 51 microcontroller infrared remote control transmitter and receiver decoding device.)

串口发送数据，字符，12864接受并显示字符(Serial port to send data, the character, to accept and display the character 12864)

利用28335的cpu-timer0的中断功能进行AD采集，并有AD校核程序(Use cpu-timer0 interrupt functions of 28335 AD acquisition, and checking procedures AD)

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

ad7812采集程序源码10位的，运用c语言言开发的，环境是KEIL 51。 可直接使用。 (The ad7812 acquisition program source 10, developed using c language words, the environment is the KEIL 51. Can be used directly.)
