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… ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

In the Arduino board, digital outputs from D2 to D8 are used to drive segments (a to g), and digital outputs D9 to D12 are used for the digits (D0-D3) of the 4×7 LED display. Note that here the ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

The clock also displays the time in large numerals. ... Once the model was completed, it was only a matter of applying the appropriate code to the arduino for control over the LED lights.

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 ...

The decorative analogue LED IoT clock has been designed in Autodesk Fusion 360 and 3D printed before being equipped with a strip of LED lights. Check out the video below to learn more about its ...
