Max7219 Scrolling LED Sign

prusaprinters

<p>I created this snap fit led sign edge that fits MAX7219 led segments. Pictured here are 12 segments but you should be able to add ans many as you want.</p> <h3>Print instructions</h3><p>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.</p> <p><a href="https://www.banggood.com/MAX7219-Dot-Matrix-Module-4-in-1-Display-For-Arduino-p-1072083.html?rmmds=search&amp;cur_warehouse=CN">https://www.banggood.com/MAX7219-Dot-Matrix-Module-4-in-1-Display-For-Arduino-p-1072083.html?rmmds=search&amp;cur_warehouse=CN</a></p> <p>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<br/> power and ground run to 5v and ground the other<br/> Clock goes to 13 // or SCK<br/> Din goes to 11 // or Data IN<br/> CS goes to 10 // or CS</p> <p>You will need 8 of the edge clips and one each of the end connector .stl files</p> <p>You will need the following arduino libraries. You can find then on github.</p> <p>MD_Parola<br/> MD_MAX72xx<br/> MD_UISwitch</p> <p>The code I am running is the MD_Sprites_Library in the MD_Parola examples.</p> <p>you will need to change the hardware type to match your hardware. The ones above are ICSTATION_HW</p> <p>Search for this line:</p> <p>define HARDWARE_TYPE<br/> and replace whatever is on that line with</p> <p>define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW</p>
