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 without some ...

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 text or picture for ...

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 ...

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...

It’s amazing what you can make with a blonk of acoustic guitar wood, a string of LED lights, and some basic coding knowledge. Surely someone with a healthy imagination could figure out various ways to ...
