I want to make a Learning (?) Board for my son that has 36 individual buttons (A-Z and 0-9) which will play unique and specific *.mp3 files (recordings of mom or dad saying each letter/number). Is this possible?
I would imagine that the easy answer is to use several Arduinos, but I'm also looking to use what I already have without the expense of buying more boards.
If you promise to write your whole project up and include photos of The Kid using it so I can put it on https://ArduinoInfo.Info I'll send you a Mega and Sensor Shield...
I have 14 grandchildren and am a sucker for KidsFunStuff
