Unity Android - Rotation camera with Joystick on FPS Controller

Hi! I founded an old tutorial how can I make two Joysticks for FPS: one to move and one to rotate camera. First Joystick was very simple, I only dragged two prefabs in Hierarchy and created an Event System and voila! My FPS moved :D but... For rotate camera with Joystick was a problem, tutorial was maded for Unity 4.6 and I have Unity 5.3.5f1, C# coding was different and not work to me. Can anyone help with my problem? I want a C# code for drag and drop into Joystick or FPS Controller and rotate my camera with Joystick.
