Week4:analog input

This week we learned analog input with arduino, connecting servo for motions and potentiometer to control the degree of intensity of the corresponding elements, like the brightness of light or volume of sound. I found it very fascinating. However, I'm struggling a bit with the arduino code and after testing out the basic set-up: making motor rotate and adjust the brightness of the light, I'd like to come up with creative applications of these analog inputs for the next week.
