Process

While deliberating on which motor to use—servo or solenoid—I ultimately chose to work with a servo due to its generally easier implementation.

One challenge I encounter is to handle with servo. Especially with smaller angles (angle < 20 degrees, in general), it sometimes wobbled for a few seconds before reaching the set position, or in some cases, it did not reach the set position at all. I invested a considerable amount of time in understanding this mysterious wobbling, only to discover I should have connected the positive wire to VUSB not 3V3.
