Arduino Uno LED Matrix Display

This project demonstrates how to use an Arduino to display a heart shape on an 8x8 LED dot matrix.

By interfacing the dot matrix with the Arduino and using the LedControl library, you can create and display custom patterns, such as a heart shape, with ease.

Components Needed

Block Diagram

Hardware Wiring Explanation:

Connect the Data In (DIN) pin of the LED matrix to digital pin 12 on the Arduino.

Connect the Chip Select (CS) pin of the LED matrix to digital pin 11 on the Arduino.

Connect the Clock (CLK) pin of the LED matrix to digital pin 10 on the Arduino.

Connect the VCC and GND pins of the LED matrix to 5V and GND on the Arduino, respectively.

Power the Arduino

Connect the Arduino to your computer using a USB cable.

Software (Arduino IDE):

Load the Program:

Open the Arduino IDE on your computer.

Write or paste the provided program into the IDE.

Select the correct board and port in the Arduino IDE under the Tools menu.

Upload the program to the Arduino.

Monitor the Output:

The 8x8 LED dot matrix will display a heart shape.

The heart pattern will be displayed for 1 second before refreshing.

Project Operation

Initialization:

The MAX72XX chip on the LED matrix is initialized.

The display brightness is set to the maximum value.

The display is cleared to ensure no residual patterns are shown.

Displaying the Heart Pattern :

A byte array representing the heart shape is defined.

The

The pattern is shown for 1 second before the loop repeats.
