hai,
i thought of doing a remote using the principle of sound waves by adopting FM Modulation. But, the problem is designing the receiver set. i am not prepared to set it mechanically. the receiver is to be plkaced inside the main box or regulator. as the push button switch is pressed, a frequency of sound generated gets modulated and detected by the receiver, but how do i adjust the speed accordingly???
anyonw who can help me with this...
