This DIY domino clock tells the time using three LED-lit tiles

Arduino TeamNovember 14th, 2020

After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own.

The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.

The unique timepiece is made out of cut MDF, acrylic, and 3D-printed outer sections. Everything is controlled by an Arduino Nano, along with a DS1307 RTC unit for accurate timekeeping.

Code, CAD files, and build instructions can be found in the project’s write-up.
