In an effort to catch a few more Zs, [JohnathonT] built a simple but sanity-saving clock ... to see: Arduino Nano, a DS1307 RTC, plus the LEDs and resistors. We think an RGB LED would be a nice ...

This clock tells time with the help of some WS2812B RGB LED. [Dushyant] debugged the clock with a regular Arduino, but when it came time to finish the project, he used an ATmega328 to create an ...

Using an Arduino Nano microcontroller together with addressable RGB LEDs, the tabletop version of the wall-mounted original Domino clock offers a great way to learn more about controlling LEDs ...

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 ...

Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a sentence I ...
