Digital clocks are extremely useful and generally considered pretty easy to read. ... The clock relies on an Arduino Mega to run the show, with an RTC for timekeeping and a temperature sensor to boot.

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232… ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

Discover a 3D-printed DIY 7 Segment Clock powered by Arduino Uno, stepper motors and a DS3231 RTC module. Designed for tabletop use, it features precise mechanical movement and digital control, making ...

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.

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. I designed it with Autodesk Fusion ...

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...
