Hi folks,

Did I have to declare the pinMode (out put or input) in the setup fonction for analog pins ? as I do for digital Pins ?
Why not ?

thank you

No you do not.

Why not ?
The analogRead() function does it internally when you call it's function. You only need to deal with pinMode statements if you are using the analog pins as digital pins.
