Animal Sound Game

Animal Sound Game is a game designed to test players knowledge. Players will be shown a series of animal images and played a series of sounds. Afterwards, they will be prompted to input which sound they thought was the correct one. This is repeated until the last image, and the user is informed of their score.

Images are loaded onto a raw partition on an SD card attached to the uLCD. Sounds are loaded onto an SD card interfaced to MBED. An I2C capacitive touch pad registers inputs via a software interrupt routine. A speaker and audio amp play animal sounds.

The program flow begins with a welcome screen and 4 second wait, followed by a prompt to press 0 to begin the game. Once 0 is pressed on the touchpad, the first image of a bear is displayed. Three sounds are played, two incorrect and one correct. After this, an image asking the user to select which sound they think is correct is displayed on the LCD. The user is then informed whether they are incorrect or correct on another image. This is repeated twice more. At the end, the user is thanked and the number of correct answers displayed.
