Interfacing 8×8 LED Matrix with Arduino

Circuit-Diagram-8X8-LED-Matrix-Interface-with-Arduino

This tutorial will show how to interface a 8×8 LED matrix with Arduino. Example code is provided.

LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display few characters in it.

LED Weather Forecast using Raspberry Pi

FJFLPYYIN943NGB.MEDIUM

AughtNaughtZero @ instructables.com posted his latest project, a LED matrix visualizing data from a weather website such as temperature, pressure, humidity, wind speed etc.

This project utilizes a 6 x 16 matrix of RGB LEDs to visualize a weather forecast pulled from the Weather Underground API. A Raspberry Pi runs a python program designed to fetch weather forecast data from the API at regular intervals, parse the data into temperature, pressure, humidity, wind speed, chance of precipitation, and weather condition arrays, and then colorize and display that data across the LED matrix.

DIY Morning Feed With LED Matrix

FS676X3IN4QEF6N.LARGE

Here is a LED matrix able to show useful information such as weather forecast, temperature and stock updates. The matrix is controlled by a Particle Photon board.

You wake up in the morning. You’re groggy. You grab your phone lazily and start browsing. You check the weather, your stocks, your instagram. Before you know it, you’re running late! Do your mornings look like this too? We’ve been there! We wanted to streamline our mornings so we built a morning feed so that we can get all the info while we brush our teeth.

Large 8×8 LED Matrix Display

FCKQUY7ILCHCS11.MEDIUM

jollifactory @ instructables.com has published a large 8×8 LED Matrix Display which is driven by a MAX7219 and Arduino.

For this project, we will be building a single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. Each of these 8×8 LED matrix modules is around 144mm x 144mm in size.

How to build your own 8×8 led matrix

resistors-in-matrix-top

circuitspecialists.com has published a new guide on how to build your own 8×8 LED Matrix on a prototyping board. In a later guide they will show how to program it using an Arduino Compatible board.

Today we will be starting our adventure into the deeply complex, yet totally incredible world of LED Matrices. This post will be the first of an entire Arduino Matrix Programming series by Circuit Specialists.

Building the Colossus LED Display

by Adam Haile @ maniacallabs.com:

The 2014 NC Maker Faire was a huge turning point for Maniacal Labs. It was there that the idea for the AllPixel and what is now BiblioPixel got their start. It’s also where we showed off our first custom-built LED display, the 24×24 LPD8806 matrix. At nearly 24 inches square, and 1 pixel per inch, it was certainly impressive. But we left the Maker Faire with a desire to go bigger. Not just more pixels… but physically larger. Much larger. We call it “Colossus”.

Tutorial on the Design & Implementation of an FPGA RGB LED Matrix Driver

In this episode Shahriar and Timo demonstrate the design methodology of an FPGA based 32×32 RGB LED matrix driver. Timo has kindly devoted some of his time to describe the block diagram and the thought process which goes into designing this type of FPGA display driver. The various components of the overall system (PLL, UART, and Display Controller) are shown along with the simulation data. The outputs of the Spartan-6 FPGA board are then measured using a Keysight S-Series oscilloscope. The design of the RGB matrix is also demonstrated using a custom clock interface sent wirelessly to the unit via Bluetooth.

by Tustin High T-Tech @ instructables.com:

The purpose of this small scale LED marquee is to display messages to our classroom in a more modern and centralized way. In the classroom, this construction would save white board space and is convenient because it can store a large amount of information. It is also fairly simple to program and has a mount, making it easy to place anywhere within the classroom setting.
