The code for the spelling game

Arduino
This game shows a picture on the ILI9341. On the keyboard, there are 10 drawings.
After pressing one of those keys a Picture of the animal appears on the screen, the name is written on the LCS 16x2, and a track with the sound plays on the mp3. Then after you type it on the keyboard if the name is correct it sounds music to celebrate .
