How to make a character rotate depending on its speed?

Question

Game development

Passany, help! I'm making a trial game on UE to master the engine. In this game, the character is a donut (:D), and he moves by rolling. I work with blueprints and so far everything is done as always - with the help of crutches. It just starts to rotate when you press the movement button. I need the donut to rotate depending on the speed of its movement in space, because with the gamepad you can smoothly move the stick and the speed of the character will be different. It seems to me that this can be implemented as a wheel, but I don’t know how to do it. I hope you understand me. So... help.
