BOX 777 is an interactive installation inspired by the "fortune cookies". It’s designed to be placed in public spaces such as on a tree or in a street corner where it can catch people by surprise. When someone comes close, the system wakes up and displays a set of short, uplifting messages which direct people for the next stages. A joystick allows users to move through the options, and when the button is pressed, a slip of paper is printed with one of the messages. The goal is to create a simple and playful experience that invites a short moment of reflection.The project was built around an Arduino Uno microcontroller, forming the brain of the system. It included a set of synchronized components: CODE STRUCTURE The system is activated when the HC-SR04 ultrasonic sensor detects someone within 25 cm. Based on the joystick's direction, different short texts appear on the LCD screen: Up (North): “it’s great to see you!” Left (West): “today / needs magic?” Down (South): “push the button for ticket” Right (East): “till we meet / again!” If the joystick button (SW) is pressed, the DC motor rotates for approximately 350 milliseconds. This motor movement pushes the paper roll forward slightly, allowing the user to tear off and collect a small fortune message. When no one is detected nearby, the system turns off the screen to save power. DC Motor + Transistor Circuit: controls the physical movement of a paper roll inside the box, pushing a slip forward like a fortune ticket. Breadboard Power Module + Capacitor + External Adapter: ensures the entire system runs with stable 5V power, preventing voltage drops especially during motor activation. After assembling and testing each electronic component, I designed and built a custom actual box for the system using lightweight materials. The layout was carefully planned so that the screen, joystick, and paper slot would be visible and intuitive for passersby. The mechanical mechanism was optimized to push just a few centimeters of paper on each interaction. Finally, the entire process from early mockups to wiring, box construction, and real-time testing was captured in video and edited as a storytelling piece that documents both the technical development and the conceptual journey of BOX 777.
