[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. The software uses a custom ...

the idea is that he can still use the Arduino to reprogram the NVRAM chip when he wants to play around with the sound. We’ve covered some pretty fancy circuit bent instruments here in the past ...

The price difference between the two boards is minimal too ... especially when used in simple circuits like the Arduino's built-in examples. If using the board to familiarize yourself with ...
