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.

Inside the boxy blue base is an Arduino Nano, a DS3231 real-time clock module, and a perfboard full of transistors for switching the LED strips inside the segments.

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 three hands ...

The so-called Doodle Clock is an Arduino -powered robotic arm that's been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it ...

Instead, Make shows you how to build an internet-connected alarm clock using an Arduino and Google. All you'll need is an Arduino Yúnm a touch screen, a USB speaker, and a few cables.

Arduino enthusiasts or those looking to build a DIY binary clock may be interested in a new shield created by developer Marcin Saj. The Arduino binary clock shield has been made available via the ...

To make things a little easier on yourself, Arduino shield-maker 1Sheeld shows off how to hack a clock to change color depending on traffic conditions.

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino-based DOTKLOK. Basically, you can get a bunch of different ways to tell time. Different ...
