Time has gone by since my first post about the sound box… I already wrote a couple of articles about the button pad here, here and here. I finaly came up with something. I did build an autonomous sound box which can act as a piano or act like an MP3 player.

It is based on an Arduino Mega, a Sparkfun’s 4×4 button pad and its associated PCB, anamplified Adafruit’s Music Maker, and a Sparkfun’s MMA8452 triple axis accelerometer breakout board.

There are 3 modes which are demonstrated in the following videos

Player mode

In this mode, you first select a “bank” and then a file to play. Sound / music files are stored and the SD card inserted in the Adafruit’s Music Maker. File is read from the SD and played by the VS1053.

Piano Mode

Here, I use the MIDI mode of the VS1053. You first select a “bank”. Each bank has a specific set of sounds mapped to pad buttons.

Tilt Mode

This mode is quite simple for now : the light is moving using Sparkfun’s MMA8452 triple axis accelerometer data.

What’s next

In following posts, I will go into details of the Sound Box, hardware and software, how to assemble everything…

There is plenty of stuff that could be done : voice or music recorder using microphone input on the music maker, piano record mode, more advanced tilt game, “simon says” game…
