[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.

What does one do with old circuit boards and projects? Throwing them out doesn’t feel right, but storage space is at a premium for most of us. [Gregory Charvat] suggests doing what he did: ...

1. Arduino Nano Microcontroller: This small yet powerful microcontroller will be the brain of your clock, handling all the logic and control for the LEDs. 2.

If you are considering purchasing a Nixie tube clock kit you may be interested in a new Arduino project published by Doug Domke to the Hackster.io website ...

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.

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