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 ...

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 ...

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 ...

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 ...

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. “ ...
