MAX7219 LED Array Sign. These parts comprise a frame that fits around 12 8x8 led array segments. You can find them here in 4x arrays. You will need 3 of them. https://www.banggood.com/MAX7219-Dot-Matrix-Module-4-in-1-Display-For-Arduino-p-1072083.html?rmmds=search&cur_warehouse=CN Solder 3 8x8 4 device led ends together and connect the 5 wires out the end with the opening. Run the 5 wires to an arduino power, ground din, cs and clock power and ground run to 5v and ground the other Clock goes to 13 // or SCK Din goes to 11 // or Data IN CS goes to 10 // or CS You will need 8 of the edge clips and one each of the end connector .stl files You will need the following arduino libraries. You can find then on github. MD_Parola MD_MAX72xx MD_UISwitch The code I am running is the MD_Sprites_Library in the MD_Parola examples. you will need to change the hardware type to match your hardware. The ones above are ICSTATION_HW Search for this line: #define HARDWARE_TYPE and replace whatever is on that line with #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW
