Hi. I am making my own game console with arduino uno with lcd display (2x16). I do not have a lcd keypad sheild and I need one. So how do I make my own on breadboard (or just connect the buttons and such)? I also do not know how to connect the lcd and buttons and code them to make game at ALL. I am complete noob. So please teach me how to make my own lcd keypad sheild. I have some breadboard of the rectangle and tiny ones. Please help.
Before investing your hard to come by money I suggest watching a bunch of online tutorials. Look at things like alarm clocks, temperature displays etc, that will teach you the basics you need to pick a display. I simply use the ones that are controlled by a I2C module that plugs in to the back of the display. Do not expect to accomplish this in a few short weeks, the initial learning curve is very steep. Also do some of the tutorials on basic electronics so yo can pick up some of the terms.

So why not buy one? It is probably cheaper than making your own.
If you don't know how to wire a LCD, look at the LiquidCrystal examples that come with the IDE.
You can google for LCD keypad shield. Most pages will have a link to a schematic. I can not vow for the correctness but this was the first one that I found: https://www.elecrow.com/wiki/images/5/56/LCDKeypad_Shield_V1.0_SCH.pdf. It shows a set of buttons and how they are wired.
Alternatively, if the number of pins is no limitation, just wire the buttons directly. Button between pin and GND, use pinMode(yourButton, INPUT_PULLUP).
