通过把音乐的节奏转变成字符以实现通过高低电平让蜂鸣器响...

采用高发射功率红外光电二极管和高灵敏度光电晶体管组成。 光缝宽度（分辨率）有0.8mm、0.4mm两种。-High transmit power infrared photodiode and high-sensitivity phototransistor. Optical slit width (resolution) of 0.8mm, 0.4mm two kinds.

此包包括以HD4478位控制器的LCD说明，另外有一89c51为例，采用直连方式编写的lcd驱动程序，效果为将要显示字符以左滚动方式双行显示，难度不大，但体现部分原理，水平不高，共同进步！-HD4478 to the LCD controller note, another example of a 89c51, with Direct Connect approach to the preparation of the LCD driver and the results will be revealed for the characters to the left of double rolling basis, not more difficult, but embodies some principles, the level is not high, and common progress!
