Powered by an Arduino, the clock uses an articulated arm with a UV LED to write out the current time on a piece of glow-in-the-dark material.

The heart of the clock is the Arduino Uno, a versatile microcontroller known for its ease of use and flexibility. The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module.

Below the 3D print of the moon the clock shows more traditional data thanks to a 0,96” OLED screen. It not only displays date and time, but also air moisture if you need to know of such things.

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 ...

The proposed hardware setup is very easy — just connect the CLOCK (Pin 5) of M62429 to D6 of Arduino while routing its DATA (Pin 4) to D7 of Arduino. M62429 can be powered by the 5-V regulated DC ...

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.

I like this. 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 ...

Okay, I knew this would happen - one Arduino clock leads to another. Take a look at a clock that tells the time in terms of the first 192 digits of Pi, via a 32 x 8 LED matrix... Dubbed the Pi Day ...
