Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

There are LED clocks, and then there are LED clocks that can blind you from 30 paces. [Stiggalicious’s] LED ring clock is of the latter variety. 200 WS2812B/Neopixel RGB LEDs drive the ring clock to ...

Should a clock be round? Depends on the style of clock, we suppose. After all, we wouldn’t expect to see a digital clock with a round readout just for fun. But a binary clock — that’s another animal ...
