Hello,
my friend has an idea for a toy for her very young autistic children. It would be a panel with large colored buttons, lets say five of them. And when particular button is pushed, a certain melody is played. Those melodies would be uploaded to the toy somehow, preferably by USB from PC (she would like to change those melodies from time to time). It would basically be a very crude MP3 player, lets say that you could upload mp3, or any other format, named for example "1", "2" etc. and it would play file named 1.mp3 if button 1 was pushed.
So my question is: can anyone give me any idea how this can be built, or point me to some tutorials, projects that are similar? I really appreciate any help, thanks.
Sorry if this is in wrong category.
