Here is the controller I designed for my 3D printed animatronic eye mechanisms. The main advantage it has over a traditional gaming controller is the ability to fine-tune a value (such as the openness of the eyelids) using a potentiometer, which holds its position. The controller plugs directly into an arduino and is pretty easy to build. Support me on Patreon for a look behind the scenes and a Nilheim Mechatronics sticker pack: Contact: enquiries@ Discord Server: Also check the instructable for comprehensive detailed text instructions: Supplies: Joystick - either use one of those cheap and nasty unbranded ones that come in arduino starter kits (: check images to see if you might already have one) or use a Parallax Inc 2-Axis Joystick Module if you want a better response: Push-to-make switch - the controller is designed to use one of these but you could probably make any small cylindrical switch fit. 10k Potentiometer - designed to use these but again, a similar sized one is likely to fit with some adjustments. Screws: A small kit like this should do if you don't already have these lying about: 4* M3 x 4/5/6mm screws (only if using cheap joystick) 4* M2 x 4/6/8mm screws (only if using parallax joystick) 4* M3 x 8/10/12mm screws 6 core wire with an outer diameter of around : - although realistically you can use whatever cable you want! (optional) A cable grommet for a hole and wire: Downloads: Visit:
