Arduino Pro Mini 3.3V 8 MHz
At only 8MHz the Arduino Pro Mini 3.3v is slow by today’s standards but fast enough for most classic games.
Other Arduinos or compatibles can be used in its place. If an 5v Arduino like the Uno is used you must use a Level shifter from 5v to 3.3v or you’ll risk frying the TFT.
2.2″ TFT 240×320 SPI
This high quality 2.2″ TFT screen has an integrated ILI9341 controller and we will be connecting to it using Hardware SPI.
While the screen is sold as an 240×320 pixels TFT, we’re going to use it at 320×240 pixels, rotated using a simple hardware configuration switch, making it more suitable for video games.
The size is perfect for a small handheld videogame and fast enough for most classic video game titles.
The TFT screen features an SDCART reader but for now we’ll not be using it.
A joystick with 3 axis is used to control de videogame, horizontal and vertical plus fire.
The first two controls connect to the Arduino using 2 ADC pins and the fire button a regular digital pin.
Sound FX is an important component of Videogames. A small buzzer is present to provide sound feedback to the player. It can be used to play music and sound effects.
