MAX7219 LED Array Sign. These components form a frame that encloses 12 8x8 led array segments. You can locate them here in groups of four. Three units are required. https://www.banggood.com/MAX7219-Dot-Matrix-Module-4-in-1-Display-For-Arduino-p-1072083.html?rmmds=search&cur_warehouse=CN Connect three 8x8 4-device led ends together and link the five wires protruding from the end to the opening. Route the five wires to an Arduino, connecting power, ground, din, cs, and clock. Power and ground are directed to the 5V and ground ports respectively. The remaining connections are routed as follows: Clock is connected to pin 13 or SCK. Din is linked to pin 11 or Data IN. CS is connected to pin 10 or CS. Eight edge clips and one end connector STL file each will be necessary for this project. To proceed, the following Arduino libraries must be installed: MD_Parola, MD_MAX72xx, and MD_UISwitch. These can be found on GitHub. The MD_Sprites_Library from the MD_Parola examples is currently being used. To ensure compatibility with your hardware, modify the hardware type by searching for the line: #define HARDWARE_TYPE Replace the existing value with: #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW
