实现stc12c5a60s2单片机电子时钟的时，分，秒等基本功能。(Stc12c5a60s2 achieve single-chip electronic clock hours, minutes, seconds, and other basic functions)

电池保护板检测，检测电池的电压、电流和温度代码。 (Battery protection board testing, test the battery voltage, current and temperature code.)

此程序为4*4矩阵键盘，键盘自身不带电源电阻，八个接线，在程序中进行需进行软件拉高拉低以便按键扫描。 应用单片机为MSP430F5529。(4* 4 matrix keyboard without power resistors MSP430F5529)

用PIC单片机实现带音乐播放的电压表,最高实现3.3V的电压测试(PIC mcu)

基于51的C语言频率计，内涵仿真图，以实现空能(Based on 51 C-language frequency meter, meaning simulation diagram, in order to achieve air can)

stm32学习 十三：RS485总线的使用 十四：TFT屏的图片，中文和字符显示(stm32 learning 13: RS485 bus use 14: TFT screen pictures, Chinese, and character)

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.)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))

交通灯的开发，实现主道停留60秒，干道停留20秒，出现紧急情况采用按键控制(The development of traffic lights, the main road to stay 60 seconds, the trunk stay for 20 seconds, the event of an emergency using the button control)

可虛擬兩個RS-232或者是多個RS-232互傳資訊，此源码維Visual Basic所編寫。(Can be a virtual two RS-232 or RS-232 over pass each other information, this source code written by Visual Basic dimension)
