Embedded software and hardware controls

Hi! I hope to post in the correct section
I want to know if someone here has developed musical instruments with juce and embedded board (RPi or other). The question is about the user interface (physical UI), how to hook up pots, buttons and LCD display to control the parameters?

I mean the hardware side, electrical connections from pots to raspberry or from pots to Arduino to raspberry… etc.

in this way, I don’t need to develop a GUI but only write on small LCD display and take the external control’s value.

Is it possible?

Here is quite a relevant talk on the subject from ADC this year - https://www.youtube.com/watch?v=jq7zUKEcyzI
