Circuit to display a message in a 8x8 LED matrix, stored in the EEPROM memory of the microcontroller.

A good ad can display the clearest possible way the message you want to communicate, electronics has facilitated this work using different visualization methods from a simple indicator number to known 7-segment displays, to the giant color screens for reproduce images and graphics, through the displays 14 or 16 segments or arrays, made with LED lamps, with which you can easily represent letters, numbers, punctuation and spelling to drawings.

This project involves the design of a simple matrix of LEDs 8 rows and 8 columns (8x8), in which a stored in the EEPROM memory of the microcontroller circuit message, which is crossing the screen from right to left playing. A good practice to get into graphical programming, and which can be modified for use in multiple applications, I hope you enjoy it and be useful to them.

documentation is attached with the explanation of the operation of the circuit (in Spanish), in addition to the schematic diagram and the source code of the microcontroller.
