Hola Robotronic@s!! Audiobook player for mac. En este TUTORIAL aprenderemos a usar una MATRIZ LED de 8x8 con ARDUINO, entenderemos como crear letras y formas que mostraremos en nuestr.
1088AS Datasheet - 8x8 Dot Matrix LED Display, pdf, pinout, equivalent, replacement, schematic, manual, data, circuit, parts, datasheet. LED 8x8 matrix 3mm 1088AS Manufacturer: OASIS RoHS: Yes Emitted Colour: Red Face Color: Black Type: Row Cathode Column Anode Wavelength: 625 630nm Forward Voltage: 2.1V 2.5V Forward Current: 20mA Dimesions: 32mm x 32mm x 8.0mm. For this project, we will be using the MAX7219 which is an Driver IC, which works with SPI communication. An 8x8 LED Matrix has 64 Pins in total if all the cathodes are connected together. While an Arduino has only 14 digital pins, and the Arduino is not capable of providing 64 LEDs with enough current so we use the MAX7219, which needs only four Arduino pins to control the LEDs.
Overview
LED Matrix Editor - is online tool for editing and creating animations for 8x8 LED matrices. It is free and easy to use.
Usage
- Click on LED to toggle single item
- Click on row or column numbers to toggle whole row or column
- Click on icon to clear/fill whole matrix
- Shift the matrix Up, Down, Left or Right using arrow buttons
- Invert matrix via button
- Rotate matrix clockwise or counterclock-wise
- Insert, Update or Delete images
- Reorder images using Drag-and-Drop in the bottom pane
- Use browser bookmarks to save images
- Use browsing history to Undo/Redo your work
- Choose type of generated code (64-bit integers or arrays of bytes)
- Copy generated C code into your project
- Use predefined sets of fonts and icons
- Play animation with configurable inter-frame delay (in milliseconds)
- Choose matrix color
Hardware
LED Dot matrix driven by MAX7219 works perfect with Arduino
Code samples
Samples below implement this animation:
These samples use a LedControl (library for the MAX7221 and MAX7219 Led display drivers) to switch LEDs ON/OFF.
Matrix as a 64-bit long integer
State of the 8x8 matrix can be presented as an unsigned long integer (uint64_t).
In this case the code is pretty compact. Like this code for Arduino:
In this case the code is pretty compact. Like this code for Arduino:
Matrix as array of bytes
Some people prefer to operate with arrays of bytes instead of long integers.
This case is also supported. Here is example of using an array of bytes in binary format:

Animation data in PROGMEM
Arduino has limited amount of RAM. For example my UNO based on ATmega328P has only 2KB of RAM. Not very much. But it has 32KB of Flash memory. Why not to use it for storing animations? No problem. Just push this data into the PROGMEM and then read them.

About this project
This is a very easy project for starters like me, the idea of it is to show you how to send bytes to an 8x8 LED matrix.
I have programmed this with all the letters of the alphabet,if you wish to add something go HERE: http://robojax.com/learn/arduino/8x8LED/
In that link you will be able to make more shapes.
In the left hand part of the page there will be an 8x8 matrix, with all the Leds off, by clicking them they will turn on and at the bottom of the page there will be the code that represents what you are doing to the matrix, when finished change the 'sprite name ' and paste the code that you just made, in the code that I made.
Pointer focus registration code. To make this project work you will need the library:
- FrequencyTimer2
Which you can download from:
- https://github.com/rookie/FrequencyTimer2
