To drive the LEDs, [Ole] is using an Arduino. Even though the WS2812s are individually addressable and only one data pin is needed, [Ole] is using five individual data lines for this matrix.

Matrix Din to Arduino D11 Matrix CS to Arduino D10 Matrix CLK to Arduino D13 To control the matrix, I used the Arduino LEDControl library, enabling access to individual LED pixels, rows, and columns.

8x8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8x8 LED Matrix module ...

The Arduino can just increment the counter up to the appropriate LED. The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip.

3x3 RGB LED Matrix: Using WS2812 addressable LEDs for a fun, visual touch. It's connected to pin 9, and I made sure to expose the last data output pixel to make the matrix extendable. NE555 Timer: ...

Today, I'm thrilled to guide you through the steps to create your very own 32x8 compact LED matrix, driven by an Arduino Nano. For a double fun, the used LEDs are purple. Let's dive right ...
