Here is my contribution to wishing Arduino a Happy Birthday on Arduino Day 2020.

 

This is a basic project using an Arduino Nano Classic, a Slide Potentiometer and a Adafruit ILI9341 TFT screen.

Using the Adafruit TFT and GFX libraries, I have the system start up with some images and text displaying on the screen.

Then using the Touch feature of the TFT screen, I use an on screen button to start the basic Pong-type game.

I included a Pizeo speaker just to have a sound when the ball hits the paddle.

 

The pic and vid I have are not the best but they at least show something.

 

Happy B-Day Arduino!

    Jon,

     

    Thanks for all the useful details.

    Yeah, I was in a bit of a rush to get this posted for Arduino Day so it lacked much detail.  I'll see about adding more to it if possible.

    Much of what I implemented followed the Adafruit ILI9341 TFT examples using the Adafruit_GFX, Adafruit_ILI9341, SdFat. Adafruit_SPIFlash, Adafruit_ImageReader and TouchScreen libraries.  The ILI9341 TFT Breakout Board has an onboard micro SD card that can be used to read in a BMP file and display it on the screen. 

     

    I image you could use a SD card breakout board that uses a SPI interface in place of what is used on the ILI9341.

     

    This looks like this after initialization:

      ImageReturnCode stat; // Status from image-reading functions
  Serial.begin(9600);
  tft.begin();


  // The Adafruit_ImageReader constructor call (above, before setup())
  // accepts an uninitialized SdFat or FatFileSystem object. This MUST
  // BE INITIALIZED before using any of the image reader functions!
  Serial.print(F("Initializing filesystem..."));
#if defined(USE_SD_CARD)
  // SD card is pretty straightforward, a single call...
  if(!SD.begin(SD_CS, SD_SCK_MHZ(25))) { // ESP32 requires 25 MHz limit
    Serial.println(F("SD begin() failed"));
    for(;;); // Fatal error, do not continue
  }
#else
  // SPI or QSPI flash requires two steps, one to access the bare flash
  // memory itself, then the second to access the filesystem within...
  if(!flash.begin()) {
    Serial.println(F("flash begin() failed"));
    for(;;);
  }
  if(!filesys.begin(&flash)) {
    Serial.println(F("filesys begin() failed"));
    for(;;);
  }
#endif
  Serial.println(F("OK!"));

  // Fill screen blue. Not a required step, this just shows that we're
  // successfully communicating with the screen.
  tft.fillScreen(ILI9341_WHITE);

  tft.setRotation(3);
  Serial.print(F("Loading p14-logo.bmp to screen..."));

  stat = reader.drawBMP("/images/arduino-day-2020.bmp", tft, 30, 80);
  reader.printStatus(stat);   // How'd we do?
  stat = reader.drawBMP("/images/p14-logo-sm.bmp", tft, 60, 165);
  reader.printStatus(stat);   // How'd we do?
  //delay(200);

     

     

    The Pong-type game was created using the Adafruit_GFX, Adafruit_ILI9341libs to create a play field and then draw a circle for the ball and a rectangle for the paddle.  I clear the previous spot for the ball or the paddle when they move before drawing them in the new position. The colors are based on the Arduino log colors that I had to translate to RGB565 format for the display.

  • A good little game. It would be good to see more details as I would be interested in possibly making something similar. I have some small OLED displays which might also work well. How did you get the graphics into the system?
