Would like some advice on the best arduino board to use

I have been playing around with a makey makey and want to make something similar with an arduino board...

I want my input to be the same as the makey makey, so when you have the ground attached to you and you touch something conductive you get a reaction BUT instead of it initiating a keyboard press I would like it to play a pre determined sound stored in the ardunio memory and play the sound on a speaker attached to the board...therefore eliminating the need for a computer to make it work.

I want to use as small of a board as possible and wonder if anybody has any suggestions?

Thanks in advance :slight_smile:

A single note? Or some kind of collection of notes? With harmonics?

like a short sound clip...

like a short sound clip...

Can you describe what that data would look like? Playing a mp3 or wav file requires extra hardware to deal with those file types, and, of course, a place to store files.

yes a mp3 file or wav file 1-5 sec long. I would like 8-10 different sound clips stored on the ardunio. When you touched each "object" (like you would with a makey makey) it would play a predetermined sound clip. Each object would have its own sound.

Can the ardunio store the sound files with some add on hardware?

Sorry if i am not being clear enough...i have built a prototype of exactly what i need to happen using a makey makey, a wireless Bluetooth speaker and my computer. But now i want to build it as small as possible and eliminate the need for the computer to make it work.

Can the ardunio store the sound files with some add on hardware?

Yes, it can - with a wave shield or an MP3 shield. Both have SD cards and handle all this issues with playing a track.

But now i want to build it as small as possible

The minimum size is going to be that of the shield + the Arduino + batteries + speaker. In other words, not all that small.

Add a small mp3 player module that the arduino controls.
www.mdfly.com, search for MP3, they carry several.
