Proto Shield
The Arduino ProtoShield makes
it easy for you to design custom
circuits and extend the capabilities
of your Touch Board. As it has no
inherent functionality it does not
conict with the Touch Boards core
functions.
Why this shield is great
You can solder parts, like a
potentiometer, to the prototyping
area to create at volume knob for
example, or add a small solderless
breadboard on top to quickly test
circuit ideas without having to
solder.
Pins and mods
There are no pin maps or
modications necessary for this
shield to function, however check
out the Touch Board Pin Functions
guide to help you navigate and add
in your custom design.
Arduino
Wireless Proto Shield
The Wireless Proto Shield allows
your Touch Board to communicate
wirelessly using a wireless module.
It is based on the Xbee modules
from Digi, but can use any module
with the same footprint.
Why this shield is great
This is a great shield to send and
receive touch data from a remote,
untethered location. We used this
shield to make a wireless doorbell,
but could also be great for
interactive artworks or installations
that are hard to reach with cables.
Pins and mods
The Xbee wireless module that ts
on top of the Wireless Proto Shield
only uses D0(RX) and D1(TX) to
communicate with the Touch Board.
These two pins are already free to
use on the Touch Board and this
does not require any modications.
Arduino
Motor Shield
This shield has two separate motor
channels that can each drive or
sense a motor. It is based on the
L298, a dual full-bridge driver
designed to drive inductive loads
such as relays, solenoids, DC and
stepping motors. It is also Tinker
Kit compatible.
Why this shield is great
This is a great shield and is fairly
easy to modify to work with the
Touch Board. This is a key shield if
you want to change a touch event
into a physical movement. If you
are just driving the motors without
a brake you may not need to do
any mods.
Pins and mods
Motor B requires you to remove the
solder bridge at D8 on the Touch
Board, disabling the MP3 function.
To use Motor A you need to remap
D3 to D10 on the Motor Shield.
Removing all the solder bridges on
the Touch Board also allows you to
connect Tinker Kit output modules
to the shield that use D5 and D6.
Adafruit
Neopixel Shield
The NeoPixel shield hosts 40
congurable RGB LEDs. The pixels
are arranged in a 5x8 matrix and
are all individually addressable.
Only one pin (D6) is required to
control all the LEDs. You can cut a
trace and use nearly any other pin
if you need some customization.
Why this shield is great
This is an amazing shield that
we often use in demos at trade
fairs. We set it up to map raw
capacitance data on a painted
sensor connected to a touch
electrode to the LEDs to create a
visual display of proximity.
Pins and mods
This shield requires a very quick
and simple modication using a
soldering iron. Simply remove the
solder bridge on pin 6 or remap it
to another pin, like D13. The latter
option saves the MP3 functionality
on the Touch Board.
Adafruit
16-Channel 12-bit
PWM/ Servo Shield
This shield uses only two I2C
pins to control 16 free-running
PWM outputs. You can even stack
multiple shields on top of each
other to control more.
Why this shield is great
This shield is a great way to
get multiple things moving and
responding to touch. It is fully
compatible with the Touch Board,
although you may need to use
an external power source for
your motors. Denitely a good
match for interaction artists and
designers.
Pins and mods
There are no pin maps or
modications necessary for this
shield to function. You will need to
use external power for the motors.
The Touch Board’s capacitive
sensor (MPR121) has it’s I2C
address set to 5C, so keep this in
mind when altering the shield’s
default address.
Adafruit
Bluefruit EZ-Link Shield
This Bluetooth shield is a regular
‘SPP’ serial link client device and
can pair with any computer or
tablet and appear as a serial/COM
port (except iOS). The EZ-Link
can automatically detect and
change the serial baud rate and
the DTR/RTS/DSR ow control pins
are automatically synced to the
computer serial port.
Why this shield is great
The Bluefruit EZ-Link shield is the
easiest ways to get Bluetooth
connectivity to your Touch Board.
If you have any ideas for interesting
interfaces that connect to other
Bluetooth compatible gadgets
without cables, this is your shield.
Pins and mods
This shield works without any mods
as it takes commands from D0 and
D1 pins which are free for use on
the Touch Board. There is also a
nice prototyping area, so check the
Pin Function guide if you want to
add some extras on top.

Ardumoto
Similar to Arduino Motor Shield this
shield has two motor channels. You
can control the speed and direction
of your motors and it works with
motor A without any mod’s.
Why this shield is great
Get motor channel A driving a
motor in minutes with this shield.
It is the simplest way to transform
a touch event into a physical
movement.
Pins and mods
To get both motor channels
running you will need to re-map pin
D3 (PWMA) to another PWM pin
like pin D10.
