数字电子钟，单片机控制，可以设置时间，并且进行时钟计时(Digital electronic clock, microprocessor control, you can set the time and the clock time)

一个倒车雷达的程序 使用的是AVR单片机。 在include.h文件里面定义 #define CPU_F 4 //4MHZ 定义外晶振的频率 #define GOOD //40KHZ更准确 #define DIS150CM //若定义了，1.5M有效，没有定义就是2.5M有效 #define DEBUG //若定义了，则是调试模式debug , 没定义就是release模式 (Include.h document in which the definition of# define CPU_F 4// 4MHZ definition of the frequency of oscillator# define GOOD// 40KHZ more accurate# define DIS150CM// if defined, 1.5M effective, efficient 2.5M is not defined# define DEBUG// If defined, it is debug mode debug, not release model is defined as)

c语言中经常生成的hex文件简介，很全不错，可供初学者学习(good and perfect)

ansys 传热模型APDL代码，包含第一类温度边界条件和第三类温度边界条件(ansys heat transfer model APDL code, including first class temperature boundary conditions and temperature boundary conditions)

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.)

实现智能数字显示仪表。要求8位数码管显示（4位显示测量值，4位显示设定值），4输入按钮（功能选择、数码管选择、数字增加、数字减少），可设定上下限报警（蜂鸣器报警）。K型热电偶（镍铬-镍硅），测温范围为0℃~1000℃。采用比例-积分控制、并用晶闸管脉宽调制驱动1000W电加热器（电源电压为AC220V）。(Intelligent digital display instrument. Asked 8-bit digital display (4 shows measured values, four display settings), 4 input buttons (feature selection, the digital control options, the number increased, the number is reduced), upper and lower limits can be set to alarm (buzzer alarm ). K-type thermocouple (Ni-Cr and Ni- Si), temperature range is 0 ℃ ~ 1000 ℃. Proportional- integral control, and using thyristor PWM drive 1000W electric heater (power supply voltage is AC220V).)
