How to smooth an FPS camera?

Hi there, I’m currently making a first person game and I want my camera rotation (which is driven by mouse movement) to be smoothed out. I’ve been looking into it and have found some tutorials for sidescrollers and third person games, however it doesn’t seem to work properly for first person. I noticed that I might be able to use the Interp nodes, but I’m not sure which one or how to hook it up. Does anyone know how to do this?
