trying to learn simple a* pathfinding

i've been reading and reading and reading the begginer tutorials on how to use A* . My goal is a very simple project(no special graphics or anything). i want a circle from one end of the screen to go to the other end. these would be the start and goal positions. using the A* and finding the path. how would i move this circle (sprite) to the goal. im getting kinda confused on how you would do this in a game. remember im really really new to ai and trying to just get that basic shape to move around walls. how is movment of sprites done using A*. for example do you set a mini-goal being the next node working backwords? and when your sprite has reached it, change the mini goal to the next node. etc,etc till you hit the goal? allowing for frames of animation of walking between nodes? my second question which would be my second program would be how would i do it if the walls can be made at runtime,(before you figure out the path) for example as the user clicks on the map to build walls. any help would be greatly Appreciated or any advice . as for some advice, im going to reread the begging tutorial again, and maybe again after that. thanks
