四字16*16点阵电子屏字符显示器 显示字用查表法，不占内存，用四个16*16共阳LED点阵显示， 效果：向上滚动显示字，每次四个，重复循环(Four characters 16* 16 dot matrix electronics display screen characters use the word look-up table method, do not account for memory, with a total of four 16* 16 LED dot matrix display Yang, effect: scroll up words, every four, repeat cycle)

说明：  1.44寸显示屏显示资料，可显示汉字，图片，彩色图片，带取模软件(1.44-inch display screen display data, can display Chinese characters, pictures, color pictures, with the module software)

说明：  单片机实现贪吃蛇游戏，本人使用的是51单片机，显示器为16*16点整控制，此类方法适合初学者玩耍~~(Snake MCU)

超声波测距，通过声波测出距离，并打印到串口上(Ultrasonic ranging)

基于AT89S52设计的超声波测距电路，有4路距离警报灯和蜂鸣器报警电路，并有警报输出接口。资料，中包括程序源代码和原理图，其中原理图是用protel99做的。(AT89S52 based on the design of ultrasonic distance measurement circuit, a 4-way distance warning lights and buzzer alarm circuits, and alarm output interface. Information, including source code and schematics, which is schematic protel99 do.)

锁相环用于电机转速精准检测，资料很不错，值得下载(Phase-locked loop for accurate detection of motor speed)

简单的微机保护仿真程序，热切希望可以有一个交流的平台，可以学习(Simple microcomputer protection simulation program)

AMICCOM的A7128 433芯片驱动(AMICCOM A7128 433 Chip Driver)

能够进化模拟电路，同时更改参数设置可以进化自己想要的东西(To evolve analog circuits, parameter settings can also change the evolution of what she wants)

采用凌阳SECE061A板，外接发光二极管来设计一个语音跑马灯，具体功能如下： 1. 采用61板播放一小段语音。 2. 用发光二极管显示声音的大小。 3. 可以扩展为让声音一直循环播放。(By Ling Yang SECE061A board, an external LED to design a voice Marquee, specific functions are as follows: 1. By 61 board plays a brief speech. 2. With a voice the size of the light-emitting diode display. 3. Could have been extended to allow the sound loop.)
