Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

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 ...

It introduces how to download libraries for the LED Backpack and how to use it to display a scrolling bar graph of microphone input amplitude. This will effectively allow students to visualize sound ...

Since Maker LED Matrix is connectable to the internet, you can simply have any data shown at the display! Or just show any other message, picture, or animation on it. “ ...

The Arduino pings a Javascript app that pulls down tweets from The Verge and displays them on an 8×8 LED matrix display.

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...
