说明：  设计一个基于单片机的嵌入式系统，要求具备以下功能: 红外数据的接收及解码,红外发色电路 数码管的显示驱动控制 将接收到的红外数据进行实时显示(限于动态扫描方法) 请根据以上功能要求，进行硬件系统设计,编写软件程序并画出流程图。 信号波形解码显示都没问题，LED灯和蜂鸣器设计是有点问题的，可以删掉不用不影响。自动使用的是压缩包里第二个文件的程序，其他包里有额外的参考资料，可借鉴。(To design an embedded system based on MCU, the following functions are required: Infrared data receiving and decoding, infrared color circuit Display drive control of digital tube Real time display of received infrared data (limited to dynamic scanning method) According to the above functional requirements, design the hardware system, write the software program and draw the flow chart. Signal waveform decoding display is OK, LED lights and buzzer design is a bit of a problem, can be deleted without affecting. Automatic use of the second file in the compressed package of the program, other packages have additional reference materials, can be used for reference.)

说明：  C51系列单片机，用C语言编写，使扬声器发声(C51 series of microcontrollers, C language, so that the speaker sound)

There is an increasing demand today for motor control circuits, as a result of the incredible proliferation of automated position control equipment, which is itself made possible by recent developments in the field of digital computation.

说明：  使用51单片机，通过BH1750获得光强值，数据处理后，使用lcd1602显示。(The light intensity value is obtained by BH1750 using 51 single chip computer. After data processing, it is displayed by lcd1602)
