- Lesson 15: MAX7219 LED Dot Matrix Module. Run a simple sketch provided in the Elegoo tutorial, using LEDControl and LEDMatrixDriver libraries. A beginner's guide to the Most Complete Starter Kit by Elegoo.
Hello everyone, I'm Rick the Tech Enthusiast here with the next Lesson number 15 “MAX7219 LED Dot Matrix Module”. This is the next lesson on my Arduino UNO Series covering the Most Complete Starter Kit by Elegoo. I try to follow the included tutorial and will point out any changes or corrections as I find them.
As mentioned before, I purchased this Elegoo starter kit and Elegoo isn't sponsoring me. I just thought it would be fun to do a video of each Lesson as I was learning the Arduino environment.
For this video, we’ll need a few things from your Elegoo Arduino UNO kit. I’ll list the items below. In this lesson we’re going to check out the MAX7219 LED Dot Matrix Module provided in the kit. I’ll step through the Elegoo provided tutorial and briefly explain how code makes this happen. We’ll build and configure a simple circuit that is provided in the tutorial to demonstrate the functionality. The sketch used a software SPI driven Library, and then we’ll install a hardware SPI library and see some of the differences. I hope you enjoy it.
Parts you’ll need for the tutorial:
* Elegoo Arduino UNO R3 board
* The MAX7219 LED Dot Matrix Module
* Five female-to-male jumper wires
The next lesson will be Lesson 16: GY-521 Module.

Thanks for watching
Thank you for sharing this informative video! 🐻🖐🏻
Thank you for this tutorial!
Perfect tool for creating sprites! Thanks!
Thank you Rick!
hi, when i try to run the code marquee text, it seems to work. however, when the text runs over the matrix there are a couple of pixels in row 4, 5, 6 disappearing before they show up again in row 7 and 8.
havent changed anything in the code example except the ANIM-DELAY.
when running other simple code. the affected pixels work. thanks for any input.
this is a great kit! i got it
thanks sir
Thank u sir
This is a cool product I would like to have something like that to show
signals being sent on each wire LIKE a USB monitor. Do you use the
atmega328p? I switched to my other account. Can you use that thing for ARtoolKit I wish I knew the fuzzy logic in video Analytics like to update robotron graphix to like SMASHTV This chip seems great for debugging like usb or input debugger and perhaps register int INDEX debugger in nested for loops.
I'm using the Elegoo Arduino Uno clone which is using the ATmega328P. I'm not familiar with augmented reality toolkit. But perhaps it can.
This seems like a simple question but do you know how to do an OR or XOR with actual hardware on a breadboard? Is AND a short circuit like a bridged chipset? PS ctrl + > is my fav hotkey At 14:57 you need hold shift
Wow, good question. Off hand I'm not sure. I'll Google it and reply back if I find something.
@@rickmorenojr I didnt find anything on stack ex either. Perhaps bridging only works to lower a pin. but theres the sync or clock cycle I dont know how that works yet.
@@ramaclub6281 If the TTL outputs are open-collector you can do wired AND.
Do u have a website i can get on at all
Great tutorial with discussion of errors sideways printing or speed delays. Do you think leds can have a plastic spring and be used as a momentary switch too. Also I have this keyboard with graphic pads overlapping circuit lines. I think its broken perhaps microscopic capacitor thing going on. Perhaps that board was misprinted and the overlap should be on the underside of the PCB -openInvent.club
Well, LED are like a diode. They act as a one way valve. LEDs have no mechanical parts. Check out Lesson 11, which goes over a membrane keyboard type module.
@@rickmorenojr Thanks for replying to all my posts. I wanted to use them like a MASCHINE CONTROLLER they cost like 300-600 bucks. I think I can do it with two diodes and use same led legs for a momentary switch. Or A plastic like swiss army knife tweezers. With aluminum or copper tape for circuit board prototyping.
Where can I download the excel sheet from thanks
It should be available at the GitHub link. github.com/rmorenojr/ElegooTutorial
Select the Lesson 15 link, then download LEDGraphicToHex.xlsm
