F. Final Prototype

The final prototype is as shown. I got a bit of trouble when the Link1B failed by 3D printing, but I've bought some wood sticks and use those sticks to fix the Link1B. The failure was an error of tolerance when using a low-quality 3D printer so I have to cut it off a bit. There is also 1 error of the slider and I also fixed it with wood pieces. Finally, I want to share my experience that you shouldn't use a glue gun when attaching the pin and the ring, use gorilla glue instead and that will be a lot better. The Arduino needed to connect directly to my computer so I hand it a bit pendently, but everything worked fine.
