Alguien me podría ayudar con este proyecto
#1
Buenos días a todos,

Era para preguntaros que falla en este código, ya que levo semanas intentándolo arreglar pero sin éxito, seria de gran ayuda decirme que falla. 

Muchas Gracias

A qui tenéis el Código:

Código:

Buenas noches.

He unido o juntado los dos códigos en uno solo y me compila sin problemas, utilizando como base tus dos programas copiados.

Si has leído la respuesta que te puse en la otra publicación, veras que juntar dos códigos no es tan difícil, lo acabo de hacer en 10 minutos, porque no conocía los sensores ni las librerías, y eso me ha llevado mas tiempo.

Voy a hacer algo que no me gusta, y es pasarte el código, prefiero que cada cual aprenda a su manera y con la información mas que suficiente que pueda encontrar.

Me debes una cerveza

Código:
#include <OneWire.h>
#include <LiquidCrystal.h>

#define ONE_WIRE_BUS 9
