Help for LCD connection and code for simon says

Projects General Guidance
1

Hi, Im new to arduino and programming in general and I wanted to include a LCD screen that shows the score and highscore of my Simon says project, but i don't really know how to start and how to do it, in terms of programing and connections.
here is my circuit. Thanks in advance

There is example code like "blink en LED", "Blink without delay". Have You tried any of them?7

What is the setup supposed to do and what does it actually do?-

Please post real schematics, not a coloured bird nest picture.

I would suggest an I2C enabled version of the 1602 or 2004 LCD. That only needs 2 pins instead of 6.

Then use the hd44780 library to control the LCD. The library comes with extensive documentation and example code. Install the library using the IDE library manager.
