Objective:
In this project, we will use OSOYOO Basic board to drive an 8×8 LED matrix and display letters from A to I in the LED matrix.
Parts:

1 pc Osoyoo UNO Board uno-o
1 pc 8×8 LED matrix ultrasound-o.png
8 pc 220 ohm resistance
1 pc breadboard BREADBOARD

Circuit Graph:
8x8led

download code and copy/paste the code onto Arduino IDE, then run the code.

Open the serial window on the upper right had corner of the Arduino IDE, you will see result as shown in the following image:
8x8ledresult

The LED matrix will repeat displaying letter “A” to “I” one by one.
