What Is It

The RGB LED matrix is a multi-color screen that can display various information like text and patterns.

How It Works

The RGB LED matrix is composed of 64 RGB LEDs spread in an 8x8 grid. When the screen shows an image, each of the RGB LEDs represents a pixel that makes up the image. Similar to a LED matrix, the RGB version shows text, numbers, patterns and animations by lighting up and off the specified LEDs.
All LEDs in the grid have their own unique coordinates as well. The LED located at the top left corner is defined as the origin (0, 0); whilst the one at the bottom right corner is (7, 7).

You can find blocks that control the RGB LED matrix in the tab Looks in Codecraft.

Extension Knowledge

Up to 9 RGB LED matrices can be connected to one mainboard in a time. We can order their numbers according to the switch contacts on the back of them.
Note: The number order should be consistent to that of their contacts.

Once contacts are set and the modules are powered on, they will show their corresponding numbers too.
