Got stuck while brainstorming for my new project.
I’ve got an analog input selector for my stereo but… I wanna make it arduino. And double the inputs (already got an exact copy of the stereo)
The schematics for the input selector are quite straightforward. In big lines:
4 signals come in, go to a rotary switch, one of the signals will be send forward. (see attachment)
To increase them analogly I’ll just have to circuits with an increased rotary switch (8 positions instead of 4)
The thing is I want to be able to use a rotary encoder… Why? So I can keep turning the knob instead of moving in forward and backwards… Besides I’m able to use a remote control.
Here’s where my head is starting to glitch…
I could simply use 8 relays with input… But I’ll get a clicking noise each time
So I’m wondering is I could use like a 4 channel analog switch like a dg411… (or two to get 8 channels) and if yes… How I should connect this
If I look at the data sheet the chip will need 4 different signals… But I’m kinda hoping I could do it with less
