If you are considering purchasing a Nixie tube clock kit you may be interested in a new Arduino project published by Doug Domke to the Hackster.io website this week providing full instructions on ...

“So for instance, you can have one Arduino with a button, another Arduino connected wirelessly with an LED, push the button and turn on the LED without any additional single line of code to handle the ...

The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.

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 ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult with… ...

Brent Graham's clock is as unusual as it is beautiful. It’s amazing what you can make with a blonk of acoustic guitar wood, a string of LED lights, and some basic coding knowledge.

DOTKLOK Is A Hackable, Open-Source, Arduino Clock. Also Neat Looking. Contributor. ... LED colors come in red or green. The only down side is the price (starts at $150).
