Arduino-controlled, Individually Addressable RGB LED Clock

A fully custom-built digital clock featuring an 11×21 individually addressable RGB LED display, designed, programmed and assembled from scratch.

The project includes over 1,200 lines of Arduino code, automatic brightness adjustment via an ambient light sensor, a battery-backed real-time clock, hourly chime, physical controls and a fully reprogrammable design.

Every electronic connection was hand-soldered, while the white-painted wooden enclosure was cut, assembled and finished by hand, making it both a functional timepiece and a complete hardware and software design project.
