21st Century Learning and Teaching

ONLY 3 WIRES!!

This post is about the WS2812B LED strip, which is an addressable RGB LED strip. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others.

The dot matrix that we’re going to use in this guide is a 8×8 matrix which means that it has 8 columns and 8 rows, so it contains a total of 64 LEDs.

The MAX7219 chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board.

I think the best option is to buy the dot matrix with the MAX7219 chip as a module, it will simplify the wiring. You can check the dot matrix at Maker Advisor and find the best price.

You can control more than one matrix at a time. For that you just need to connect them to each other, as they have pins in both sides to extend the dot matrix.

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller.

Two common questions we receive:

How can I use more than one 8x8 matrix backpack in an Arduino sketch?

Can I have two (or more) matrices always showing the same image?

This tutorial demonstrates both.

We’ve had spooky Halloween displays on the brain lately, but the concepts here are equally applicable to more innocent schemes!

An 8×8 dot led matrix is a very interesting device because with proper instructions the individual leds or any group of leds can be programmed to fire. This characteristic, plus the feature that up to eight modules can be daisy chained, forms the basis for a nearly endless series of visual effects. Here we discuss the very basics of working with one MAX7219 dot led matrix module. A simple sketch is provided that creates a ‘smiley’ followed by a simulation of a bouncing ball.

In our previous blog post (Tutorial…), we were playing around with a LED MATRIX <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Scrolling Text with 8×8 LED MATRIX  <===> and we will continue to use the LED MATRIX, but this time with a Wi-Fi connection. We will use the module “ESP8266” which you can purchase worldwide around as it is very popular and it costs ONLY 7.49 €.
