Just found this Youtube guy. He just finished a 6 part tutorial on making animatronic eyes and blinking eyelids.
Pretty much a basic start to finish thing!

He covers setting up the controller, making the eyes, doing the code work, etc.
He also shows a neat system of controlling the eyes and eyelids via a joystick and hand clapper device.
He uses these tools to move the animatronics in a record format VS tedious code writing to make the movements.
His eye assembly and controller tools are all 3D printed if you're so inclined or want to pay to have them printed.
I believe he offers the info on that. As mine will be for a doll head, I will have to make my own anyway.
Going downtown. Gonna see my gal. Gonna sing her a song. I'm gonna show her my ding dong! C&C
