Hi friends, I want to realize an automation for my aquarium. I want to check
- The illumination
- The temperature
- And then other sensors for some parameters, but this part I will make it later.
I have written this code, can you check it? Before that I load it in Arduino I'd like to know your opinion. Thanks.

..
because it has to assume a value less 25.
