As I said i'm really new on coding so I don't really know what am I doing,
As you wish to implement a moderately complex project I suggest you take some time out to learn the basics. Study some of the examples that come with the Arduino IDE and get familiar with C++ coding.
Then break your project into small parts - for example read a sensor and display the value on the Arduino Serial Monitor, and display "Hello World" on your display screen, etc. Don't try building a composite program until you can do all the parts separately.
