Switched all lights on manually for demonstration purposes. The green lights indicate that the outer ring is closed, there's one light for each entity. The six yellow lights next to the green ones show that the ring is opening or closing. When the ring is fully opened, the red lights are on. The two yellow lights in the middle indicate movement of the eye lids. While an opening or closing sequence is running, no further input is accepted.
The circuit sequentially opens the ring, opens or closes the lids and closes the ring again. How that works is explained in detail in my
logic thread.
