This time post we will discuss in full about Running Text using Dot Matrix 8×8.

Running text is display digital the that contains information example text or images

Materials needed are as follows:

· Arduino Uno

· Arduino IDE software link:

· Dot Matrix Led Module 8 × 8 (MAX7219 Displays)

· Jumper Cables

· Dotmatrix link program:

schematics wiring Arduino uno with Dotmatrix MAX7219 as shown images below :

Configuration pin

Follows step by step:

Install Arduino IDE until complete.
Extract The program that was downloaded earlier by extracting it here.
Save the extract to the folder: C: \ Program Files \ Arduino \ libraries
Open folder: C: \ Program Files \ Arduino \ libraries \ MD_Parola-master \ example \ Parola_Scrolling.
Or open the Arduino application that has been installed:

• a. Select file

Change the text as desired:

char newMessage [BUF_SIZE] = {“WELCOME TO MY OFFICIAL CHANNEL ACHIGAWA”};

• e. Check

• f. Connect Arduino uno with a laptop or PC check list connect at Tools

1. Board >> Arduino/Genuino Uno
2. Com/Port

• g. Upload

h. If using 2 Max7219 (8×64) it must be changed

define MAX_DEVICES 4

to 8

GOOD LUCK. BYE BYE
