You have already posted the same question here https://www.8theme.com/topic/slider-revolutuion-4/#post-238261 and I have explained what options you need to use.
Have you created a carousel type of Revolution slider? Unfortunately, the creation of the user content is not included in our support. I could try to explain some Revolution slider options that you maybe don’t understand, or even edit them if you already created a slider but we can’t create slider for you from scratch and edit it according to your needs because we are not personal content managers, sorry. So, create the carousel type of the revolution slider, enable loop, enable autoplay https://www.themepunch.com/slider-revolution/module-general-settings/#slideshow
