8x8 LED Matrix Animation

8x8 LED Matrix Animation

Introduction

This experiment demonstrates how to control an 8x8 LED matrix and create simple animations using the Arduino.

8x8 LED Matrix

Components Needed

Circuit Setup

  1. Connect the 8x8 LED matrix to the Arduino using jumper wires, ensuring that the rows and columns are properly connected.
  2. You may use a shift register or driver IC like the MAX7219 to control the matrix.

Ensure the LED matrix is wired correctly for proper operation.

LED Matrix Circuit Setup

Code for LED Matrix Animation

Upload the following code to your Arduino to animate the 8x8 LED matrix:


#include 

const int dataPin = 3;
const int clockPin = 4;
const int loadPin = 5;
LedControl lc = LedControl(dataPin, clockPin, loadPin, 1);

void setup() {
  for (int i = 0; i < 8; i++) {
    lc.shutdown(i, false);       // Wake up the display
    lc.setIntensity(i, 8);        // Set brightness level
    lc.clearDisplay(i);           // Clear display register
  }
}

void loop() {
  for (int col = 0; col < 8; col++) {
    for (int row = 0; row < 8; row++) {
      lc.setLed(0, row, col, true);  // Turn on a single LED
      delay(100);
      lc.setLed(0, row, col, false); // Turn off the LED
    }
  }
}

Explanation

The code uses the LedControl library to control the LED matrix. The animation is created by turning on and off each LED in a specific order.
