- Hi , I am AIT-LASRI YOUNES Last week we organised a NEXT to play with LED matrixes and Arduinos. This was part of ".
A future instructable will show how to work with mulitple LED matrixes connected together.
*For this example, you need the following components:
- Arduino Uno board
- MAX7219 Red Dot Matrix Module
- 5 jumper wires F/M (female/male)
-Although this instructable uses an Arduino Uno board, you can use other Arduino (compatible) boards
-You can find the matrix module at many online stores (e.g. http://dx.com/p/max7219-dot-matrix-module-w-5-dupont-lines-184854). This includes a 8x8 LED matrix (red colour), a MAX7219 chip to control the LEDs, header PINs and sockets, one 10KOhm resistor, a 100nF capacitor, a 10uF electrolic capacitor and a PCB where everything is connected together. You can purchase the module already soldered and mounted or just the components. Up to you;-)
-If you want to learn the low level details, you should check this article at arduino playground.
-IMPORTANT: The LED matrix is common cathode. This module does not work with common anode matrixes.

Step 2: Arduino Library :
----------------------------------------------------------------------------------------------------------------
- the LED matrix is controlled from the MAX7219 chip through an Arduino Library.
This instructable is based on the LEDControl library. You can read a very clear and detailed tutorial about this library at arduino playground.
The nice thing about this library is that you can connect up to 8 matrixes together to build larger displays (more about this in a future instructable).
- the LedControl library has been updated with several new methods to simplify the display of characters and strings. The new version of the library is available here (chose your preferred compression format: zip or rar)
*To install the library in your Arduino IDE:
- uncompress the library file that you just downloaded
- make sure that you close all the open windows of the Arduino IDE
- look for the libraries folder inside the folder where you installed the Arduino IDE (see picture)
- copy the uncompressed LedControlMS folder (the folder with all its content) inside the libraries folder
-If everything worked fine, you can now open the Arduino IDE again. If you go to File-> Examples, there should be a tab named LedControlMS with four files inside it.
