7128芯片设计原理图，适合3A一下电流的步进电机驱动器设计，非常实用(7128 chip design schematics for what current 3A stepper motor driver design, very practical)

使用stm32的一路pwm控制RGB灯条的颜色和个数随着音乐跳动。简称音乐喷泉(The color and number of STM32 PWM control RGB lights are beating with music. Music fountain for short)

全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)

基于51单片机的实验 用于驱动直流电机的c程序(Based on 51 single-chip experiments used to drive DC motor c program)

说明：  T2 定时器应用简例，利用T2定时器控制小车的调速与测速功能的新定时办法(T2 timer application simple example, the use of the T2 timer to control the car' s speed and the speed function of the new timed approach)

本内容为LCD12864的驱动函数，可以适合刚入手液晶屏的同学学习(The content LCD12864 driver function can fit LCD classmates just start learning)

Test ifnonnull extends DxTestCase.

说明：  这是一个基于DS1302时间发生芯片和AT89C51单片机的万年历程序(err)

通过光明电阻检测实现对光源的自动追踪，并在LCD12864显示对应光照强度。(The light source is automatically tracked by light resistance detection, and the corresponding illumination intensity is displayed on LCD12864.)

驱动，用于解决arduino uno r3在计算机不被识别问题(Drive to solve the problem that Arduino uno R3 is not identified in the computer)
