Matriz 8x8

Este pequeño proyecto es para aquellos que quisieran regalarle un recuerdo a alguien especial, esta hecho con una matriz de leds de 8x8.

Armado

---

Para el armado hay varios ejemplos ya hechos en la red y de uno de esos escogimos el siguiente:

para elaborar las conexiones usamos Fritzing
