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.

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino… ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult with… ...

There’s no shortage of Arduino-based clocks around. [Mr_fid’s] clock, though, gets a second look because it is very unique looking. Then it gets a third look because it would be very di… ...

We have feature quite a few cool clocks here at Geeky Gadgets, the latest one is the work of Andrew O'Malley, the DOTKLOK, which is an open source Arduino digital clock.

Sean took an antique clock an removed the mechanisim, and then replaced it with an Arduino, that is programmed to check the weather on the Environment Canada website every fifteen minutes.

The Arduino binary clock shield has been made available via the Crowd Supply website with preorders starting from $33 and worldwide shipping available from $6, and commencing during August 2019.

You’ve doubtless seen those ubiquitous clock modules, especially when setting clocks for daylight savings time. You know the ones: a single AA battery, a wheel to set the time, and two or thr… ...

The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.
