Push joystick and Rotate actor during second

hi guys, i want some tips about the actor rotation in blueprints .
if i want the player to push the joystick left or right to rotate a cylinder with smooth rotation , where should i start first ?

i would look at the third person for an example but the basics are to use the add yaw input node and an axis mapping

this is my first attempt … each time the player press the “B” button on the controller, le cylinder will move 45degrees . but i can’t see a smooth animation while using the world delta seconds … how can i make the movement for 2seconds for example
