Arduino - LED Scrolling Text ~ Simple & Easy

Hello Friends, This is the Simplest method to make Scrolling Text on LED Matrix using Arduino. You can buy a 8x8 LED Matrix or make your own (more cheep) following this guide. https://www.instructables.com/id/Make-a-8-x-8-LED-Matrix-Cheap-and-Simple/ . Sorry for my English cuz I don't know it well.

Part List

• Arduino (UNO)
• LED Matrix (8x8)
• 8 x 220ohm Resistors
• 8 x 10K Resistors
• 8 x 2N2222 / 2N3904 Transistors

• 4017 IC
• Dot board (To assemble the circuit)

Now we need to Assemble the circuit to Drive this Matrix. It consist of 4017 Decade counter.(See the diagram) and assemble the circuit. Connections to Arduino are shown on that.

Upload this Code to your Arduino.

Replace "www.instructables.com - DJ Sadeepa" with the text you need to be displayed.

So Connect this to an External power source or let it to operate with USB Power, you will see the text displayed on The arduino.
