How would I go about scrolling a name across a LoL shield with a potentiometer?
You know how wide the display is. You know how wide the text is. You know the position of the potentiometer. With those you can determine where in the text (if the text is wider) or display (if the display is wider) you need to start drawing from and where you need to stop drawing. Subtracting the text width from the display width will give you the range for performing linear interpolation with the pot position.
