Neo Pixel LED Digital Clock

In this project, I created a digital clock using WS2812b neo pixel LEDs. The digits are in 7 segment display format. I used acrylic sheets to make the enclosure.

Parts used:

• Arduino nano x1
• RTC module x1
• WS2812b LED x30
• Wires
• USB cable to power/program/set time
• Cardboard/Acrylic sheets to create enclosure and cut out 7-segments
• Glue and tools as required

The challenge with the code was to illuminate the correct LEDs corresponding to different digits. I acheived this using pre-defined arrays for corresponding numbers.

You can download the code from the below link,

Above is how I wired the LEDs. I cut out 7 Segment digits out of a card board. It will be easier if you can use a laser cutter.
