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
Código
También pueden ver el código en GitHub
