For YouTuber Jroobi, merely walking up to his front door, inserting a key into the lock and turning the handle was too simple, which led him come up with a very unique and high-tech design for a new type of lock. His idea was to combine several different kinds of verification/control mechanisms, including codes, RFID and voice, all into a single package.

The sci-fi-style device he created consists of two Arduino boards: a Nano that handles the physical electronic strike assembly that blocks the door from opening, as well as receiving input from a slightly modified Google Home smart switch for voice operation via the Google Assistant ecosystem. Connected to the Nano is a Due, which is responsible for driving the 7″ touchscreen and everything else within the door controller. The central screen displays smooth animations for entering passcodes and scanning RFID tags, while a string of RGB LEDs just inside the door illuminate depending on if access was granted. Lastly, futuristic-sounding instructions and effects are played with the help of a DFRobot MP3 player module.  

For more details about how Jroobi made this project, you can watch the demonstration video below or read his post here on Reddit.
