This is a personal project I worked on over the summer. The switch at the top really does open or close my door; it sends a command to my proxy server which routes that command to the Arduino IoT cloud server, and then the Arduino is connected to a motor driver and DC motor that reels a fishing line around my door handle.

For now, I don't plan to add more automation. This project was made to allow my girlfriend full access to my room w/o needing a prox, and partly by my real problem of locking myself out frequently. So, it was fun to learn about Arduinos and circuitry along the way.

All the parts I used, including 3D-printed components and code, are open source on the Github Repo. Feel free to try making one yourself!
