Hello friend, this is the easiest way to scroll text on LED matrix using Arduino.
You can buy 8x8 LED matrix or make it yourself (more cheep)
Follow this guide. .
Sorry, because I don't know much about English.
Now we need to assemble the circuit to drive this matrix.
It consists of 4017 ten-year counters. (See photo)
Assemble the circuit.
The connection to Arduino is shown above.
Upload this code to Arduino. Replace "www. instructables. com -
DJ Sadeepa "the text you need to display.
So connect it to an external power supply, or let it operate with a USB power supply, and you will see the text displayed on the arduino.
