Automated Door Lock

thingiverse

I built an automated door opener that lets our dogs go in and out whenever they want, giving them complete freedom of movement around the house. Frustrated with not being able to find an electronic lock that worked seamlessly with my door opener, I decided to build one myself from scratch. The lock is powered by an Arduino system, which also controls the opening of the door itself. A continuous rotation servo takes care of the rotation, but note that the hole for the servo is slightly undersized - I had to file it a bit to get a snug fit and prevent any issues. To ensure precise printing, use a "fine" setting on your 3D printer. The latch is designed to close the door 10mm in front of the door frame, providing a secure seal every time. After some thorough testing, I made some adjustments to improve the lock's performance. I added "Spindle 8", which has a slightly smaller thread diameter and runs much more smoothly than before. Additionally, I shortened the part so that it could be easily attached to a servo gear using glue, creating a stronger connection between the two. UPDATE: To protect the lock box from dust and debris, I added a cover that fits snugly over it.
