Hello:
This is my development about a MP3/WAV sound board to emulate the audio tape cartridge system in Black Fever/Attack pinballs, also may work like sound board in Torpedo/Underwater, and to emulate xylophone in electromechanical pinball.
Also may use it for any application whe need play MP3 or WAV sounds, may play directly up to 14 sounds, each sound play when put a pin to ground in connector, and by programm may play thousands of sounds.
All sounds stored in micro SD card, so may store many files and big only limited by size of your micro SD card.
