Introduction: Scrolling Text on a 8x8 LED Matrix Using an Arduino UNO

This instructable will explain how to scroll text on an 8x8 matrix

Step 1: Materials

  • Arduino UNO
  • 1 or more MAX7219 matrix modules
  • 5 wires
  • Solderless breadboard

Step 2: Wiring

  • Connect the 5V on the arduino to VCC on the matrix
  • Connect the GND to the GND
  • Connect input10 to CS
  • Connect input11 to DIN
  • Connect inpot13 to CLK

Step 3: Adding Another Matrix

Connect the VCC,GRD, ect., to create a daisy chain

Step 4: The Code

This is the code and library you'll need to run the matrix.

Step 5: Modifying the Code

    This works great, except the text scrolls bottom to top on an 8x32 display instead of across(32 wide by 8 high) it. Am I doing something wrong? It's like 4 rows of text zipping by from the bottom to the top (top to bottom depending how your holding the display.)

    I can only get this to work with up to 4 matrices no matter what I set #define maxDisplay as. What might I be doing wrong?

    I'm sure I could find a use for something like this as I'm working on a smart home project. Excellent work., thanks for sharing.

    Cool. This would be a good way to setup alerts for a smart house system.

    Great work, especially for a beginer like your self!
