Objective:
In this project, we will use Arduino UNO board to drive an 8×8 LED matrix and display letter from A to I in the LED matrix.
Parts:
1 pc | UNO Board | ![]() |
1 pc | 8×8 LED matrix | ![]() |
8 pc | 220 ohm resistance | ![]() |
1 pc | breadboard | ![]() |
Circuit Graph:
download code and copy/paste the code into Arduino IDE, then run the code.
Open the serial window on the upper right corner of the Arduino IDE, you will see result as following image:
The LED matrix will repeat displaying letter “A” to “I” one by one.
