The file 'MAX7219 LED Array Sign 3D Printer Model' is (stl) file type, size is 3.6KB.
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.
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
