How to Create a Matrix Configuration 18 X 18 Pixels for Your LED Display
If you want to create a stunning LED display for your home or business, you need to know how to configure the matrix of your LED pixels. A matrix configuration is a way of arranging the pixels in rows and columns to form a rectangular grid. The matrix configuration determines how the pixels are addressed and controlled by the LED controller.
One of the most common matrix configurations is 18 x 18 pixels, which means that there are 18 rows and 18 columns of pixels in the grid. This configuration allows you to create a square display with a resolution of 324 pixels. In this article, we will show you how to create a matrix configuration 18 x 18 pixels for your LED display using Arduino and NeoPixel.
What You Need
To create a matrix configuration 18 x 18 pixels for your LED display, you will need the following components:
An Arduino board (such as Arduino Uno or Nano)
A NeoPixel strip with 324 RGB LEDs (such as WS2812B or SK6812)
A 5V power supply (such as a USB cable or a battery pack)
A breadboard and some jumper wires
How to Wire the Components
To wire the components for your matrix configuration 18 x 18 pixels, follow these steps:
Connect the 5V pin of the Arduino board to the positive (+) terminal of the power supply.
Connect the GND pin of the Arduino board to the negative (-) terminal of the power supply.
Connect the DIN pin of the NeoPixel strip to pin 6 of the Arduino board.
Connect the GND pin of the NeoPixel strip to the GND pin of the Arduino board.
Your wiring should look something like this:
How to Program the Arduino
