I found an LCD screen that has 4 ports, 2 being 5v and gnd; the others being called SDA and SCL. The LCD screen has 4 lines that can be written, my main goal is to set up the LCD screen so that when my rover 5 drives in different directions it is written on the screen. Also if read the forum before this one my rover 5 is going to go into harmful gases, detecting if they exist in different areas. If it does i want to put a warnings on it, etc so it can be read.
My main concern with this is how to connect the LCD screen and a basic code that would print something simple like "hello world" onto it, from there i can infer what i need to do for my different print statements or whatever term is used to do this.
