Hi! i need an help.
io have a Bare Conductive touch board for elettric paint (it has arduino core so the programming has the same IDE).
The basic touch mp3 sketch use the digital INPUT E0-E11.
/*******************************************************************************
Bare Conductive Touch MP3 player
------------------------------
Touch_MP3.ino - touch triggered MP3 playback
You need twelve MP3 files named TRACK000.mp3 to TRACK011.mp3 in the root of the
microSD card.
When you touch electrode E0, TRACK000.mp3 will play. When you touch electrode
E1, TRACK001.mp3 will play, and so on.

TRACK000.mp3
TRACK001.mp3
TRACK002.mp3
TRACK003.mp3

TRACK011.mp3

i need to add the ANALOG INPUT, A0-A5 in this sketch (they should became E12-E17).
i know i can convert analog as digital input.
but i dont understand where and how to put this instruction...
any advice?
thanks
