Required Hardware
- Led Matrix 8×8 Bi-Color
- Arduino Board
- Breadboard
- Jumper Cables
With this tutorial you learn how to connect and display the word “Hello” to Led Matrix 8×8. Below is the wiring that you need only for the red color.
Wiring
To wire your LCD screen to your Arduino, connect the following pins:
- Led Matrix Pin 1 –> Arduino Pin A1
- Led Matrix Pin 3 –> Arduino Pin 5
- Led Matrix Pin 4 –> Arduino Pin 11
- Led Matrix Pin 6 –> Arduino Pin A2
- Led Matrix Pin 7 –> Arduino Pin 7
- Led Matrix Pin 9 –> Arduino Pin 4
- Led Matrix Pin 10 –> Arduino Pin 6
- Led Matrix Pin 12 –> Arduino Pin A0
- Led Matrix Pin 13 –> Arduino Pin 10
- Led Matrix Pin 15 –> Arduino Pin 12
- Led Matrix Pin 16 –> Arduino Pin A3
- Led Matrix Pin 18 –> Arduino Pin 2
- Led Matrix Pin 19 –> Arduino Pin 8
- Led Matrix Pin 21 –> Arduino Pin 3
- Led Matrix Pin 22 –> Arduino Pin 13
- Led Matrix Pin 24 –> Arduino Pin 9
Recommended Software
- none
Hello,
I this source code am intrested because I have arduino uno I have 8×8 led matrix, but I couldn’t display text on it,
I have no source code that will carry my text and display, please help me through.
during the upload skeeth shoowing the error what i do

Where can I find the whole alphabet of the letter arrays?
I would like to display text in Matrix Bicolor (2 color) – Thank you
