Display Text at P10 LED Display Using Arduino

Dotmatrix Display or more commonly referred to as Running Text is often found in shops as a means of advertising their products, its practical and flexible in its use that encourage business actors use it as advertising advice. Now the use of Dotmatric Display has spread, not just as advertiser media only, as well as prayer schedules, warning boards, queuing machines, etc.

Here, we will give a post about Dotmatix Display programming tutorial using Arduino.

Step 1: Materials You Need

You will need:

Arduino
P10 LED Display Module
DMD Connector

Step 2: Wiring Connection

Connect P10 LED Display with arduino according to pin configuration above. Here we use DMD Connector.

Step 3: Connection

Installation of module like picture above.

Step 4: Code

After proper installation, next is the programming process. Before that you need a supporting library that must be installed on Arduino IDE. To download the DMD library click HERE. Next upload the program below to display a text.

// Insert file Library
#include <SPI.h>
#include <DMD2.h>
#include <fonts/Arial_Black_16.h>

SoftDMD dmd(1,1);
// Number of P10 panels used X, Y
DMD_TextBox box(dmd, 2, 1, 32, 16); 
// Set Box (dmd, x, y, Height, Width)

void setup() {
  dmd.setBrightness(10); // Set brightness 0 - 255 
  dmd.selectFont(Arial_Black_16); // Font used
  dmd.begin();     // Start DMD 
  box.print("SFE"); // Display TEXT SFE
}
