Hey there im new to this forum and i dont know if this topic already exists (btw im sorry if this post comes two times but the last one got lost somewhere i think)
Anyways here is my problem:
I want to build a hifi-system to which my raspberry shall be the data base for mp3 files and spotify and stuff. Basically to manage what input comes out of the hifi-system in the end. I think about using the Hifi-Berry or something similar if there is somthing that fits more to what i want to do.
So firstly i don't really know how i can create an input with for example a 3.5 jack plug so that i get and audio signal from an external device (smartphone or something) to the raspberry and the raspberry then gives it to the amp/hifi-system.
And secondly does anyone know if the Hifi-Berry uses all the GPIO-pins or not so i can use some of them to control some LED stripes or is there any different or better way to control them?
I am thankful for every idea or answer to these questions
