Simplified 3D Printed Animatronic Dual Eye Mechanism

By referring to the graphic, upload the code to the arduino and wire everything up. Check the Adafruit guide if you need help setting up the servo driver board. All servos should now be powered and in their neutral position, so use this opportunity to link up all the servo arms to the servos with the eyes facing straight forward in a neutral position. You can just plug them in, then disconnect the power to screw them in properly. The y-axis servo arm is in an awkward position to accept a screw, but I found that it held fine without a screw anyway. If yours doesn't, it may be helpful to remove one of the eyelid servos to screw it in. I'd recommend testing the motion with your joystick at this stage to make sure there are no issues.

For the eyelids, its best if you set the servos to be in the blinking position so you can line them all up in the centre. Do this by either holding down the blink switch or creating a short over it. Once all the servo arms are in position, its easy to screw them in.

Your model should be complete! If you want to see how to make the realistic eyes, check my previous instructable. I'm also planning on releasing an instructable soon to show you how to make a controller, so check back if you're interested!
