Pi Time is a psychedelic clock made out of fabric and Neopixels, controlled by an Arduino UNO. The clock started out as a quilted Pi symbol. [Chris and Jessica] wanted to make something more around… ...

An ATmega328 in the form of an Arduino controls the device with the aid of a DS1307 real-time clock for timekeeping and a 4017 decade counter to assist with scanning the display.

With the City Clock, you calculate the time by adding every digit vertically. The first floor equals one, second equals two, third equals four, and the top equals eight. Using this system, it’s ...

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 ...

In the world of making cool stuff with an Arduino, strange clocks rule the land. We won’t even point you to a specific one, just check out this Google search and its 481 000 results. Luckily ...

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 ...

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...

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 ...
