Hi,
I went back to the project and I am with a doubt.
I will use two timers and two relay (chiller and heater), the timer I switched the pin "temporizador1" to 47 and "temporizador2" for 48 who are orinalmente the pin ozonizadorPin and reatorPin that were disabled in the code.
had already spoken to Fernando and he said he could.
my doubt is whether these PINs will straight to relay or have to have some CI between the Arduino and the relay as unl2003?
