Controlling LED Matrix Array With Arduino Uno (Arduino Powered Robot Face)

This instructable shows how to control an array of 8x8 LED matrices using an Arduino Uno. This guide might be used to create a simple (and relatively cheap display) for your own projects. This way you might display letters, numbers or custom animations.
A 5 matrices array used in one of our robot projects (“Rob da Alegria”) is used as an example to ilustrate this technology. You might found more about this project in the following links:https://hackaday.io/project/12873-rob-da-alegria-joy-robot
