sharepoint 2013 event receiver

Hello everyone,

I have a solution and it contains many web parts inside of it.

I want to add a new event receiver with item added event for a sharepoint list. on this itemadded event, I want to add a new member to my sharepoint group.

so, when I add my event receiver, these web parts doesnt work. How should i add this event receiver to my project that should work regardless of other webparts?

should I create a new feature and add this event receiver inside of it?
