Hello! So I have a project where i am going to have a input 3.5mm switch Stereo. So what i wanna do is to get the Arduino to register button press through the 3.5mm input. Because I have very low experience using 3.5mm input there is probably missing information here, so please ask for more information about the issue.
This is the things i have to work with. Please also tell if I need anything else:
