智能电网综述。提出新的概念和研究方法。及其对目前传统电网的颠覆。(smart power grids。)

串口传输温度数据，ds1820，数码管显示带小数点(Serial transmission of temperature data, ds1820, digital display with decimal point)

一个简单的贪吃蛇程序，asdw键控制蛇上下左右，会一直加速，可以保存最高记录，可以通过改很少的参数改变界面大小、蛇的初速度与加速度。(A simple Snake program, asdw control the snake up and down, will always speed up, you can save the record, you can change a few parameters change the interface size, snake initial velocity and acceleration.)

利用单片机定时器产生高低电位各0.5毫秒的方波，该方波再经二阶滤波变成1K赫兹的正弦波，即为音频信号(To produce high and low potential of each 0.5 ms using SCM timer Fang Bo, the square wave and then by two order filter into 1K Hz sine wave, namely for audio signal )

说明：  系统由单片机、显示器等部分组成，利用显示器来显示密码锁输入的相关信息，系统上电时内部默认三组数字密码（4位或4位以上）；密码输入正确则打开密码锁(The system is made up of single-chip microcomputer, display and other parts. It displays relevant information of the password lock using the display. When the system is powered up, it acquiers three sets of digital Ciphers (4 bits or more than 4 bits). If the password is entered correctly, it will open the password lock.)
