- this runs through a loop that starts at 0 (pos = 0) and ends when the servo position
- reaches the limit. this will continue to loop until the end condition is met.
- the last value is the amount that the servo moves in degrees.
- once you develop your project idea, experiment with these values! remember to re-upload your code
- if you change anything.
