Touch-to-MP3 code for multiple (up to 7) Bare Conductive Touch Boards.

Touch electrodes 0 to 11 on the primary board to play TRACK000.MP3 to TRACK011.MP3 from the primary micro SD card.

Touch electrodes 0 to 11 on the first secondary board to play TRACK012.MP3 to TRACK023.MP3 from the primary micro SD card.

Touch electrodes 0 to 11 on the second secondary board to play TRACK024.MP3 to TRACK035.MP3 from the primary micro SD card, and so on.

The maximum total number of boards is 7 (one primary board and six secondary boards). All boards must share a common ground connection, with TX on all the secondary boards commoned together and connected to RX on the primary board.

The first secondary board must have a connection between its A0 and A0 on the primary board.

The second secondary board must have a connection between its A0 and A1 on the primary board, and so on.

Each board must also be powered, although up to 4 boards can share power by commoning up the 5V connection between them.

• You should make sure that you have followed our Setting up Arduino with your Touch Board tutorial before using this (or any other) of our code examples


1. Close the Arduino IDE if you have it open.

2. Download the .zip or clone the repository to your local machine - if downloading the .zip, extract the contents somewhere that suits you.

3. Take the primary_mp3_board folder and the secondary_mp3_board folder and move them to the Arduino Sketchbook Folder. This will be different for each operating system:

   Windows

   Libraries\Documents\Arduino

   or

   My Documents\Arduino

   Mac

   Documents/Arduino

   Linux (Ubuntu)

   Home/Arduino

   If this folder does not exist, create it first.

4. Reopen the Arduino IDE - you should now be able to open the sketches in the File -> Sketchbook menu.
