顾名思义,幅度调制 (AM)在发送信号之前调制幅度,而在频率调制 (FM)中,在通过天线发送之前调制信号的频率。在无线电台,他们使用频率调制来调制信号,然后传输数据。现在,我们只需要构建一个可以调谐到特定频率并接收这些信号的接收器,然后将这些电信号转换为音频信号。我们将使用本项目中的RDA5807 FM 接收模块,简化了...
https://github.com/mathertel/Radio,该库也适用于 SI4703,SI4705 和 TEA5767。 2、收音机前面的一个按钮用于调节收音机的“频率选择”模式,另一个按钮用于调频。一个小窗口用来滚动显示预设的频率(请根据你所属的地方在代码中设置)。 3、OLED 显示器用于显示调谐频率。 4、无线电模块的输出音频信号非常低,不...

“tiltradio”倾斜收音机是以色列设计师lukaor的作品，他利用arduino来研究交互设计中的极简主义。设计师将收音机和使用者体验等元素全都剥离，仅留下必要部分——收音机的AM/FM调幅/调频系统，设计师甚至把物理上的调节按钮也去掉了。使用者通过将收音机左右倾斜来实现波段和频道调节，省去了传统的调频按钮。在用户...
They all are capable for receiving FM radio stations in stereo with European and US settings and can be controlled by using the I2C bus. However there are differences in the sensitivity and quality and well on receiving RDS information from the stations. ...
