The movement is provided by a Raspberry Pi 3, with an Adafruit Stepper Bonnet.

it takes 200 steps to rotate the sun gear once.
it takes 400 steps to rotate the planet gear once.
it takes 1000 steps to rotate the ring gear once.

first we have 5 rotations of the sun gear, which gives us 0.5 rotations of the planet gears (per 1 rotation of the sun gear) and 1 rotation of the ring gear (for all 5 rotations of the sun gear).

next we have 2.5 rotations of the planet gear (2 rotations of the sun gear rotation of the planet gear) which gives us 1 rotation of the ring gear.

last we have 1 full rotation of the ring gear
