[rabbitcreek]’s project consists of a Adafruit Feather board hooked up to a DS3231 RTC breakout and a HS-225BB servo, which turns the clock’s hand.

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.

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.

Adafruit has this week added two new add-on boards to their ever-growing range of Feather development boards and accessories with the launch of the DS3231 Precision RTC FeatherWing, RTC and SD ...
