1) What can you do to rotate the motor clockwise in a seemingly smooth fashion?
Answers may vary. Possible Loop: EM 2, EM 3, EM 4, EM 1
2) How can you achieve a very specific rotation of 36°?
The central rotor has 25 teeth and it takes four steps for the gear to shift forward by one tooth, as it aligns successively with magnets EM1, EM2, EM3 and EM4. Therefore, the gear will undergo a full rotation in 25 * 4 = 100 steps. As a result, each step rotates the gear 360°/100 = 3.6°. To get a 36° rotation, 36 / 3.6 = 10 successive steps are required.
