Hi Fratello,

here we are step by step.

i did retrieve the serial number from the DS18B20. I placed it to the code and worked.

I put two sensors and now i have INT and EXT temp. I can say that they are really close the temp from two sensors.

Now i would like to ask you if the code is for the temp only or the thermostat.

I have place two LED on the porta.2 and porta.3, but i dont see any light.

Do i need to configure anything else?
