Desk Displays

The Desk Displays project operates as an embedded visual communication system driven by an Arduino Nano microcontroller. At its core, the system executes custom C++ firmware compiled and uploaded via the Arduino IDE. This firmware interprets a universal playlist definition language, which dictates the sequence, timing, and formatting of characters or pixels rendered across the output interfaces. Depending on the specific variant built—whether a dot matrix, a 7-segment display, or a 14-segment display—the Arduino Nano routes control signals through custom-designed PCBs to selectively energize the individual LEDs or segments. The hardware is physically structured using aluminium angle profiles to provide a sturdy, lightweight structural frame, secured together using standard mounting hardware and screws. Electrical connections between the microcontroller, PCBs, and display modules are established through permanent joints created using soldering equipment. As the microcontroller cycles through the playlist logic, it rapidly updates the digital I/O pins to refresh the displays, creating persistent textual messages, numerical values, or ambient visual patterns suited for desktop environments.
