I’d like to show you a WordClock I made with a single LED strip.
An ESP32 and an LED strip are the only electric parts of this WordClock. It adjusts the time automatically using NTP. The web interface allows you to modify settings like the time zone and color scheme.
Please try it out.

- A picture frame with a minimum square measurement of 200 mm is needed. The shape does not have to be square, letter or A4 size can also be used. It’s also a smart idea to use the SHIKISHI size in Japan.
