It takes a handful of LED arrays with an integrated driver, an Arduino Nano, a real-time clock module, and a voltage regulator. The software uses a custom 6×9 font and handles addressing the LEDs ...

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 ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format.

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 ...

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 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.

For playing the music, it uses the BY8001 MP3 Player module and for the alarm clock it uses the DS3231 Real Time Clock module. The home screen features a big clock, date and temperature ...

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.

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...
