[Barzok] has a very minimal clock build. It takes a handful of LED arrays with an integrated driver, an Arduino Nano, a real-time clock module, and a voltage regulator.

This clock tells time with the help of some WS2812B RGB LED. [Dushyant] debugged the clock with a regular Arduino, but when it came time to finish the project, he used an ATmega328 to create an ...

For those starting out in Arduino, there are tons of resources to get better acquainted with the community and the types of projects you can tinker with.

10 Simple-But-Fun Projects to Make With Arduino John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller.

Graham’s word clock is controlled by an arduino and a piece of open-source software that allowed him to code the clock once he found the appropriate code online.

An Arduino Nano or a Micro might be the best options If a small board sounds like the most appropriate choice.
