旋转LED的实现,实现用单片机控制电机转速，采用无线供电方式哦(Rotate the LED, achieving MCU control motor speed, the use of wireless power supply oh)

讲解 角度传感器的原理，内部结构，引脚功能，以及相关运用(Angle sensor to explain the principles of the internal structure of pin functions, and related use)

PCB设计接地指导书,指导pcb设计及人员更好的设计PC版(PCB design ground, guide the pcb design and make better PC version of the design)

PWM调光 1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：LED灯 定时器 3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

该程序是CRC校验程序，可以查看文件的校验和，这对文件本身进行校验，也可用在其它程序中检难数据正确与否(CRC procedures can view the document and check that the document itself calibration, but also can be used in other programs Frederick hard data are correct or not)

cc2430无线射频模块（基于ZigBee2006）的2004协议栈的演示程序和使用说明，刚开始学习或接触ZigBee的朋友可以借此来学习。(cc2430 RF module (based on ZigBee2006) of the 2004 protocol stack demo program and instructions for use, just learning or exposure to ZigBee' s friends can learn.)

超声波测距，能够实现汽车防撞系统超声波的测距，完全由51单片机控制(Ultrasonic Ranging)

说明：  i2c红外 小车扫描 简单程序 扫描准确(smart car scan easy program)

I2C总线协议应用,利用单片机中断实现可以记忆的时钟,程序自己已经调试过，绝对能用(I2C bus protocol applications, the use of the microcontroller interrupt memory clock, program debugging, and absolutely can)
