Programming has always been fun, and it uses a development platform like Arduino for a lot of benefits. Almost all programmers here will try to develop a game using the language they learn/practice. This helps them adjust their programming skills in an interesting and productive way. Since I introduced it, I have been a devoted advocate of Arduino and have always wanted to try something cool when I found out how cool the idea of using a graphic LCD monitor like the Nokia 5110 and Arduino to develop a game could get kicked Now. This is an interesting way to adjust some programming skills while having fun, so although you may also be interested in developing your game. Therefore, in this tutorial we will learn how to create decent games using Arduino and graphic LCD.
Competition plan:
Before we begin, it is very important to plan how your game actually works. I chose the Nokia 5110 graphics LCD monitor and joystick for hardware selection. I assume in this tutorial that you have chosen the same. Since the Nokia 5110 does not have a lot of space, we have planned the entire game within the 84 x 48 pixel resolution of our monitor. We have already produced a tutorial on how to connect the Nokia 5110 LCD to the Arduino.

Carry out the wiring
The circuit of this Arduino game is very simple, we only need to connect the Nokia 5110 liquid crystal display module and joystick with the Arduino. The complete circuit diagram is as follows
The Nokia 5110 LCD can work at 3.3V and the joystick module can work at 5V, so make sure to connect only the 3.3V LCD because 5V will be permanently damaged. The LCD communicates with the Arduino via the SPI protocol and the joystick only reads the ADC read voltage changes. The connection settings will be as follows
