This type of matrix is easy to make and program and it is a good way to learn about multiplexing.

Scrolling Text Using RGB Led Matrix 64x32 With Arduino Mega This DIY example I will guide you howto scroll text messages on RGB Led Matrix Panel using Arduino Mega board.For example, $$ A =\begin$$ is a row matrix of order 1 × 4. To keep the speed and color resolution somewhat reasonable, we've hardcoded part of the pinout so that the 6-pin data bus (2 red, 2 green and 2 blue) must be on digital pins 2 AWS D1. To make understand 8x8 matrix LED driving. The other sizes of LED character are composed of 3×5, 4×6, 5×8, and 6×7 dots. Interfacing microcontrollers and LED dot matrix displays. 8×8 LED Matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name is LED matrix.

Arduino 8×24 led matrix scrolling text using 74595 ic JanuJanuelectroanimesh Here is the code, just copy the below text and paste in Arduino ide software in your pc Here Are Many Ways To Build DIY LED Dot Matrix Display For Arduino Scrolling Text and Other Effects.Once you upload to arduino then the matrix just displays “text”! That means it’s displaying the internal function variable name rather than the argument

WLED makes a much better cycling display - but since it is targeted to led strips - only some of the effects work well. Wled matrix text The whole thing runs on a single 9V battery, which powers an Arduino Nano, HC-05 Bluetooth module, and LED matrix.
