说明：  系统工作电源AC220V 根据室内光线调节遥控灵敏度。 主控室电脑负责接收由控制终端传来的遥控信号播放相应多媒体影音文件； 通过主控电脑也可直接点播各展品文件，同时控制打开对应的展品照明； 遥控终端接收激光棒控制信号，控制开灯照明正在解说的展品，并通过通信总线通知主机播放相应文件； 通信中继器负责全部终端与主机间的双向信号传递； 扩展功能：设计上位机播放操作软件，控制照明灯亮度。 (无)

说明：  基于STC15W系列单片机，实现一种常用的MAX7219驱动的8位数码管显示模块的程序。(Based on STC15W series MCU, a program of 8-bit digital tube display module driven by MAX7219 is implemented.)

TCD1206 实现光源的采集，通过1549转换后传给单片机，单片机将数据通过串口传出( TCD1206 realize the collection source, through the 1549 conversion pass microcontroller, the microcontroller outgoing data through the serial port)

STM32F103C8T6控制PCA9685舵机驱动板(STM32F103C8T6 control PCA9685 steering wheel drive board)

基于stm32，实现4*4按键。文件中.c和.h文件可直接添加到自己的项目中(Based on STM32 development, 4*4 matrix key is realized. The. C and. h keys can be added directly to the kile framework.)

DAB数字收音机解码的开源C代码,可以供大家学习参考(DAB digital radio decoder of the open source C code for everyone to learn the reference)

AOK虚拟示波器的上位机源码，从串口获取下位机数据，然后绘制波形(AOK virtual oscilloscope host computer source, from the serial access to the next machine data, and then draw the waveform)

cks32f103c8t6控制步进电机与舵机，步进电机是28byj48，舵机频率是50hz,本人小白，希望和大家一起学习(Cks32f103c8t6 controls stepper motor and steering gear. The stepper motor is 28byj48 and the steering gear frequency is 50hz.)

keil软件开发，基于89c52单片机的pwm控制直流电机，通过4*4按键设置pwm值，并且在1620上显示出pwm的值。(Keil software development, 89C52 MCU PWM control of DC motor based on PWM by setting 4*4 key values, and in the 1620 shows the value of pwm. )

说明：  51实验21：DA数模转换 DA-PWM输出实验 * 实现现象：下载程序后DA模块上的指示灯呈呼吸灯效果，由暗变亮再由亮变暗(51 Experiments 21:DA Digital-to-Analog Conversion DA-PWM Output Experiment* Realization Phenomenon: After downloading the program, the indicator lamp on DA module shows the effect of breathing lamp, which changes from dark to light and then from light to dark.)
