There's a lot to love about the MAX7219 LED matrix module. Each module is a 4 unit 8x8 dot matrix running on it's own MAX7219 IC. This display works great as a marquee, a clock, a temperature display, as info signage, and more! If this module is no large enough for you then just daisy chain more module together. I'm no sure of the max number of modules you can chain together but I know you can add at least 4 of these modules (or 16 8x8 units) together for a larger display. I'm pretty excited about this module and look forward to incorporating it into some future projects.

In this video, you'll see how to make your own led matrix display using the max7219 IC. You'll be able to make your own 8x32 led display and program a LED display for another fun DIY Arduino project.

I purchased these on Amazon but you may want to check Ebay if you're not in a hurry to get them. I purchased mine from Amazon and only 1 worked. Was it user error or was it just a faulty module? who knows. I will purchase a couple more from another vendor because these displays could be used in a variety of projects, they make a great Arduino project for beginners, and they are fun to learn with.

Thanks for watching!
