What is the difference between RGB LED and LED matrix?

What is the difference between RGB LED and LED matrix?

RGB matrix panel displays are fundamentally different from other types of panel displays like our Flexible LED Matrix, for instance. Whereas the Flexible LED Matrix is built from a grid of addressable WS2812B LED modules daisy-chained together, the RGB Matrix Panel is actually comprised of standard tri-color LED chips.

How does an LED matrix work?

Simply put, an LED matrix is a grid of lights arranged into rows and columns. LED stands for Light Emitting Diode, so like with other diodes, electricity flows through it in only one direction – from anode(+) to cathode(-); doing so illuminates the light.

What size is provided LED matrix?

An 8 x 8 LED matrix display is used in this project to display the information. LED matrices are available in different styles like single color, dual color, multi-color or RGB LED matrix. They are also available in different dimensions like 5 x 7, 8 x 8, 16 x 16, 32 x 32 etc.

How does a LED matrix work?

How do I connect RGB matrix to a frame?

The wires should be connected to the female header of the RGB matrix, leaving a male header bare. The next RGB matrix just slides right onto this connected. Keep sliding up to 8 matrices onto the frame. The quickest way to get started with the RGB Matrix library is to check out the demo sketch that’s included.

Why can’t I use the RGB matrix library?

While the RGB Matrix library was being created a couple of bugs were found in the firmware of the RGB Matrix itself. The bugs have been fixed, however in order to use the RGB Matrix Library the firmware will need to be updated on the RGB Matrix boards.

Where can I download the RGB matrix library for Arduino?

Download the RGB Matrix Library and unzip it into the Arduino libraries directory. Usually this is located in the Arduino folder. After unzipping the folder you should have a directory with a path that looks something like this: …\\arduino-0018\\libraries\\RGBMatrix. The library files are inside the RGBMatrix folder.

How do I use the rgbmatrix library in a sketch?

As always, to use a library in a sketch start by going to ‘Sketch’ in the menu bar and select RGBMatrix from the Import Library menu. There are 8 colors made available by the library: BLACK, RED, GREEN, BLUE, ORANGE, MAGENTA, TEAL and WHITE.
