Connect external 5VDC supply’s GND, to the GND of 8×8 LED Matrix Module Note that the 8x8LED Matrix Module should be common-grounded with Arduino, ie, always remember to interconnect the Arduino GND ...

Create a matrix to draw on the LED I used the following site to draw the desired mouth shape, then copied the matrix and put it in the Arduino IDE code.

The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...

If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. Hackaday Alum [Phil Burgess] developed the device using an RGB LED m… ...

He ended up designing an 8 by 16 grid of LED’s that was turned into a game of Tetris. He arranged all 128 LED’s into the grid on a piece of perfboard.

In this video, the presenter will show you how to interface 8X8 LED matrix with Arduino development board along with the source code to be used in it.

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
