Flappy Bird for Arduino Uno with 2.4" Touch Screen

This is an implementation of the popular Flappy Bird game for Arduino Uno with a 2.4-inch touch screen display.

Hardware Requirements

• Arduino Uno R3
• 2.4" TFT LCD Touch Screen Display (ILI9341 or compatible)
• USB cable for programming

Required Libraries

Before uploading the sketch, install these libraries in the Arduino IDE:

1. Adafruit GFX Library
2. Adafruit TFTLCD Library
3. TouchScreen Library

You can install them via the Arduino Library Manager:

1. In the Arduino IDE, go to Sketch > Include Library > Manage Libraries
2. Search for each library and click Install

Game Play

• The game starts with a welcome screen
• Touch the screen to start the game
• Tap anywhere on the screen to make the bird flap and fly upwards
• Avoid hitting the pipes, ceiling, or ground
• Each pipe you pass earns you a point
• When you crash, the game over screen will appear
• Touch again to restart

Touch Screen Calibration

If the touch controls don't respond correctly, you may need to calibrate your screen by adjusting these values in the code:

#define TS_MINX 150
#define TS_MINY 120
#define TS_MAXX 920
#define TS_MAXY 940
#define MINPRESSURE 10
#define MAXPRESSURE 1000

Performance Tweaking

If the game runs too fast or too slow:

1. Adjust the frame rate by changing the value in:

   if (millis() - lastUpdateTime > 33) { // ~30fps
   

2. Adjust the game difficulty by modifying:

   • GRAVITY - How quickly the bird falls
   • JUMP_FORCE - How high the bird jumps
   • PIPE_GAP - Space between top and bottom pipes
   • Pipe speed - Change pipes[i].x -= 2; to a different value

Troubleshooting

• If the screen doesn't display properly, check your wiring and ensure the correct driver is specified (tft.begin(0x9341))
• If touch is not working, ensure pins are correctly connected and try the TouchScreenCalibration sketch from the previous project
• If the bird movement is jittery, try reducing the frame rate
• If the game crashes, make sure your Arduino has sufficient memory available
