Bigger Parola for Arduino V1 - Modular
hardware and library for scrolling text displays

Excerpt from main Parola for Arduino GitHub site

“Parola is a modular scrolling text display using MAX7219/21 LED matrix display controllers. The display is made up of any number of identical modules that are plugged together to create a wider/longer display

The aim was to create a 'lego-like' approach to LED matrix display, using standard 8x8 LED matrices. The software supports this flexibility through a scalable approach that only requires the definition of the number of modules to adapt existing software to a new configuration
The Parola software has a dependency on the MD_MAX72xx Arduino library found here The library implements functions to simplify the implementation of text special effects on the LED matrix“

Marco has kindly allowed me to post my files for a Bigger Parola version of his original PCB's which used 32mm LED matrices, on the GitHub Parola for Arduino site The Bigger Parola boards use the 60mm 8 x 8 LED matrices. Demonstation video Here
