运行于hadoop上的 MapReduce WordCount程序(Running on a MapReduce WordCount program hadoop)

说明：  IAR 工程，使用标准库，减少建立工程实践，IAR版本8.xxx(IAR Project use std periph)

红绿灯控制程序，基于stc51系列单片机(Traffic light control program, based stc51 series microcontroller)

STC单片机检测IO电平变化，并计数，接收到串口指令时，发送计数或者控制继电器输出(STC microcontroller detects the change of IO level, counts and receives the serial port instruction, sends the count or controls the relay output.)

说明：  用89C51的P1口做输出口，接八只发光二极管；P3口接按钮开关，作为控制信号的输入(89C51 to do with the P1 port output, take eight light-emitting diodes P3 port access button switch, as a control signal input)

姿态传感器又称为方向传感器，主要感应手机方位的变化，每次读取静态状态值。该代码可以读出分别沿3个轴所转过的角度(The attitude sensors also known as the direction sensor, sensing changes in the orientation of the phone, every time you read the static state value. The code can be read out respectively along the three axes are rotated by the angle)

这是一款基于MSP430F5529的外部中断的按键检测程序代码，基于TI 公司推出的MSP430F5529单片机学习板(This is a based on MSP430F5529 external interrupt key detection code, based on TI' s MSP430F5529 MCU learning board launched)

dspic33fj128mc804开发板例程，包含了按键、液晶显示、定时器中断、DMA、CAN、串口UART调试以及PWM等功能，讲解详细，可移植，初学者的福利！(dspic33fj128mc804 routine development board that contains buttons, LCD display, timer interrupt, DMA, CAN, serial UART debugging and PWM functions, explained in detail, portable, welfare beginners!)

51单片机LED流星雨灯，原理： 利用PWM来模似流星雨：将亮度等级分为8个 ，通过改变每一组LED的亮度来达到流星雨效果。因为流星雨是前面亮后面越来越暗，就像一条龙一样，拖着尾巴过来。(51 single LED meteor light, principle: the use PWM to die like a meteor shower: The brightness level is divided into eight, each group by changing the brightness of the LED to achieve the effect of the meteor shower. Because meteor shower is getting back in front of bright dark, like one-stop, like dragging tail over.)

这是一个在万能充电器中能自动识别电池极性的电路图，非常巧妙的设计(This is a universal battery charger can automatically identify the polarity of the circuit, very clever design)
