There are 6 Arduino pins plus 6 more connections you need for a parallel lcd. Many beginners struggle with connections but most of the do get over that. There is only one Arduino pin and 2 more connections for a serial lcd so it is easier to set up. Regarding the particular serial lcd with the provided link, it should run on a red 20x4 Lcd. Doing menus with parallel or serial lcds requires quite a bit of programming. Using my serial lcd on the other hand, requires minimal programming, sometimes 2-3 lines code gets you a pretty good menu. This is because my serial lcd integrates the phi_prompt interactive library to render plain text into menus. On arduino side you just print the menu text to the serial lcd and wait for a character to come back from serial port representing the user choice. All the menu scrolling and button sensing are handled by my serial lcd.
