In the past I’ve blogged about my Alfa-Zeta flip dots (one, two) and how I got them working with the Arduino platform. I’ve taken some time to turn the work into a consumable library that should make it much easier for others who want a turn-key way to drive the display.
The library is available in the Arduino IDE as well as the PlatformIO registry and comes with examples to get started. When added to a project it’ll grab all its dependencies so you can get going as quickly as possible.
Most of the heavy lifting is done by the excellent Adafruit GFX Library and it’s been updated to support 7×7 and 14×7 panels in addition to 28×7. Flip on! 🔴
