Program the shape of the servo’s movement using a tool to hold a marker for sketching waves on paper. When the servo moves from one position to the other, the movement will start slow and then speed up. Experiment with the outcome of the drawing by adding or removing transitions, adjusting the position and the duration of seconds until satisfied with the patterns made in the drawing.

Please note this resource was tailored for US schools and may require adjustments to suit UK schools.
