Use PyGame Library to Play Game Sounds with Raspberry Pi In this session we are going to use Raspberry Pi and the PYGAME functions to make a sound board. In simple terms, we are going to connect few buttons to the Raspberry Pi GPIO pins and when these buttons are pressed Raspberry Pi plays audio files stored in its memory. These audio files can be played one by one or they can all be played together. In other words you can press… |
