Create a Wireless AV Switch for Simple RCA Audio Input Toggling

[Chunkysalsa]

I'm trying to figure out the easiest way to make a simple switch that toggles between two different RCA audio inputs.

I can do it easily with a physical switch but how can I do it remotely. Either from a remote or from my cell phone (so either IR, Bluetooth, or WiFi). I'd prefer using my phone but I guess that would force me to write a simple little personal app. A good programming exercise I suppose.

I'm trying to keep things as cheap as possible. Thank you

One way is to use an analog switch.

The CD4066 is one of these. It contains 4 switches.

Each one provides a low resistance path between two pins, depending on whether a third pin has 5 volts or zero volts on it.
So, the control is digital, but the switch allows analog signals, like music, to pass.
