Escape Cable Hell With An Audio I/O Multiplexer | Hackaday
https://hackaday.com/2015/11/02/escape-cable-hell-with-a-multi-io-audio-multiplexer/
The audio amplifier has a volume control, and the inputs and outputs can be selected via button presses. An Arduino Pro Mini takes care of switching the relays based on the button presses. On the ...
Audio Multiplexing - Project Guidance - Arduino Forum
https://forum.arduino.cc/t/audio-multiplexing/120974
I'm wondering if my thinking is actually correct and whether this project is possible. I'd like to have a 3 conductor wire between two boxes (XLR terminated Mic Cable). These boxes would have the ability to transmit and receive audio as well as voltage. Without going into a whole lot of detail, could I use audio multiplexers to send and receive analog audio …

The 74HC4051 8-Channel analog multiplexer module can be used when there are many analog inputs in a circuit. In this case, one of these inputs needs to be selected and processed each time. This multiplexer can be used to select from 8 analog inputs. There are three S0-2 pins, which by giving appropriate values, one of the analog inputs is set ...
MegaMUX - 32 Channel Multiplexer Tutorial : 8 Steps …

The photoresistors are added on one side of the mux(IO 1 to 16) instead of the LEDs. I setup the output pin to be a voltage divider. Each time the pin is switched the next photoresistor will become the other half of the voltage divider and report to the analog pin of the Arduino. Download the INPUT program and upload.

A multiplexer, commonly abbreviated down to "mux", is an electronically-actuated switch, which can turn one signal into many.It routes a common input signal to any number of separate outputs. Similarly, a demultiplexer routes any number of selectable inputs to a single common output.. The 74HC4051 can function as either a multiplexer or a demultiplexer, and it features eight …

Then adjusting the output of the multiplexer via a bias circuit to bring the voltage to 0-4v and feeding it into an Arduino or Raspberry PI analog input and using a multiplexer like this seems like the easiest thing to do if I don’t want to build 16 bias stages which may interact with each other.
