本人非常支持单片机设计DIY 在这里再次献出小弟的一点心意,下面是使用AT89S52驱动74HC4015,实现1选择8的数据通道切换器,可以在不8个通道出加上不同大小的电阻.可以用来单声道音量的大小控制. 下面作品图是小弟设计的廉价的 基于单片机的毕业设计 ,它还使用了无线接收发送模块,通过使用手上的遥控器能控制音量的大小,还加了一块HCF4052用于输入音道的选择,支持思路音频信号的输入,一路音频信号的输出: -I very much support the single-chip design DIY here again gave a little boy s mind is to use the following AT89S52 drive 74HC4015, to achieve a choice of 8 switches the data channel, you can not add the 8-channel resistance of different sizes. Can used to the size of mono volume control. The following work plan is designed小弟cheap graduation based on single-chip design, it uses the wireless receiver send module, through the use of the hands of the remote control can control the volume size, but also Add a piece of HCF4052 Road for the importation of sound choices, to support the idea of audio signal input, the output audio signal all the way:
