Spin around an object 360 degrees

I have an object in a level that I want to be able to click the mouse and spin around the object 360 degrees. My thought is to place a character at the center of the scene and have a spring arm with a camera attached to it. I followed a couple tutorials and have my Mouse X and Mouse Y inputs set up, but I can’t seem to get any rotation no matter what I try. Does anyone have a simple, good example of how to achieve this?
