How the assign of the pins works?.
The entries will be depleted in the order they appear in the whole PinAssignment that goes from 0 to 15 for a total of 16, the value of the integer in each position will 
reference the pin to be used. Then the value that must be entered in the integer will be shown to observe the desired pin.

In case you do not want to show anything on that channel, just assign 00 so that the channel will not be written.
The pins that do not appear in the table can not be used because they were not considered in the arduino programming, to avoid overloading the
arduino and obtain more satisfactory response times.

SPANISH
Funcionamiento de la asignacion de pines.
Las entradas se deplegaran en el orden que aparezcan en el entero PinAssignment que va del 0 al 15 para un total de 16, el valor del entero en cada posicion referenciara 
el pin a utilizar. A continuacion se mostrara el valor que se debe introducir en el entero para observar el pin deseado.

En caso de no querer mostrar nada en ese canal basta con asignar 00 para que el canal no sea escrito.
Los pines que no aparecen en la tabla no podrán ser utilizados por que no fueron considerados en la programacion de arduino, esto para evitar sobrecargar al 
arduino y obtener tiempos de respuesta más satisfactorios.
