The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

The clock is powered by an Arduino Mega and it uses a DS3231 RTC to keep the time. Each digit has two sliding grids which are affected by small stepper motors.

Underneath each one is a strand of fiber optic filament powered by an Arduino Nano development board which controls the colors of the clock and a DS3231 RTC module to manage time.
