The block displays the custom pattern on the 8×8 Dot Matrix Display.
Learn how to interface an 8×8 LED dot matrix with an Arduino Uno board. Follow our step-by-step guide to set up the circuit diagram and implement the code
8*8 Dot Matrix with Arduino
In this project, we will explore how to effectively use the 8×8 LED dot matrix with an Arduino Uno board. The 8×8 LED matrix contains 64 LEDs arranged in an 8×8 grid, forming a versatile display module. By connecting each row and column to digital pins, we can control the LED matrix and showcase a wide array of patterns, emojis, and animations. Additionally, cascading multiple dot matrices together enables us to expand the display without the need for extra pins.
Circuit Diagram
Code
- Add when Arduino starts up.
- Initialize the display module and pin connections with the Arduino.
- From control palette add forever block.
- To display any emoji or pattern use the display block.
- Chose any of the emoji or emotion and add in the forever loop and add a time delay.
- Again chose one different emoji or emotion and add a time delay.
- With this your script is complete and upload the C++ code in the Arduino using the upload button.
