Hardware Overview and Features
Don’t snap apart your LilyPad ProtoSnap Plus until you're ready to use the pieces in a project. If you leave
the pieces attached to the board, you'll be able to prototype and test your project before you start sewing.
The LilyPad ProtoSnap Plus features twelve LilyPad components connected to a LilyPad microcontroller by
conductive pathways called traces. For reference, each component on the ProtoSnap has a nearby label with its
name and the number of the LilyPad USB Plus sew tab it is connected to.
LilyPad USB Plus
The LilyPad USB Plus is an Arduino-compatible microcontroller similar to the LilyPad Arduino USB - ATmega32U4
Board but with some additional features and three additional sew tabs. It is currently only available on the LilyPad
ProtoSnap Plus.

Features:
USB port for connecting to a computer.
Two sets of power (+) and ground (-) sew tabs.
Built-in RGB LED attached to pins 12 (R), 13 (G), and 14 (B).
A row of six white LEDs attached to pins 15-20.
Charging circuit for single-cell (3.7V) Lithium-Polymer batteries.
Some of the sew tabs on the LilyPad USB Plus have special functionality:
An 'A' in front of the number denotes a tab that can function as an analog input. These sew tabs can read
sensors that output a varying voltage like the light sensor built into the ProtoSnap Plus.
A '~' symbol in front of the number indicates that tab supports PWM (Pulse Width Modulation) output.
These tabs can output an "analog" signal that can be used to vary the brightness on LEDs, etc.
Note: The "A" in front of analog sew tab numbers in your code is optional. However, do not include the "~"
symbol for PWM outputs. It is only provided to make it easy for you to check which pins can produce PWM
(analog) output and is not used in programming.
Below is a table that lists the components connected to the LilyPad USB Plus sew tabs.

Powering the LilyPad ProtoSnap Plus
The LilyPad ProtoSnap Plus can be powered in two ways:

https://learn.sparkfun.com/tutorials/lilypad-protosnap-plus-hookup-guide?_ga=2.234157401.659504291.1516640116-204410570.1509632255 4/23
If you have a USB power source available (a computer, 5V USB wall adapter, USB battery pack, etc.), you can
run the board from a USB cable.
If you’d like your project to be more portable, you can easily attach a rechargable Lithium-polymer battery to
the board. See Technical Notessection for more information on batteries and charging.
Exploring the Sample Circuit
Don’t snap apart your LilyPad ProtoSnap Plus until you're ready to use the pieces in a project. If you leave
the pieces attached to the board, you'll be able to prototype and test your project before you start sewing.
The LilyPad ProtoSnap Plus ships with pre-loaded code that showcases all of the LilyPad pieces connected to it. To
power up the ProtoSnap Plus, connect it to your computer using a micro-B USB cable or attach an E-Textiles Battery.
Then slide the switch on the right side of the LilyPad USB Plus to the ON position.
The board has two modes to choose from: when the LilyPad Slide Switch (the other switch at the bottom right of the
board) is turned OFF, all of the LEDs will turn on in sequence. When the LilyPad Slide Switch is turned ON, the white
LEDs on the LilyPad USB Plus will form a bar graph showing the ambient light level - move your hand over the Light
Sensor to see the level change. And if you press the LilyPad Button (at the bottom left of the board), you’ll be treated
to a short song.

Continue to the Setting Up Arduino section for directions on installing the LilyPad USB Plus support for Arduino to
enable you to upload your own custom code.
Using the Expansion Ports
The LilyPad ProtoSnap Plus features five expansion ports connected to sew tabs on the LilyPad USB Plus. These
allow you to easily attach external components to the board, including LilyPad and non-LilyPad boards. The
expansion ports can accommodate alligator clips, IC clips, and other temporary attachment cables for testing and
experimentation. Below are a few ways to connect an alligator cable to the sew tabs.

Using Expansion Port A9
You may have noticed that tab A9 is connected to both the LilyPad Slide Switch and an Expansion Port. You can only
use A9 for one of these connections; either the switch as an input or the expansion port as an input/output.

If you’re using an external component or sensor on expansion port A9, move the slide switch to the OFF position to
keep the switch from interfering with your input or output signal.

testing.

COPY CODE
Note: The LilyPad ProtoSnap Plus and the LilyPad USB Plus requires Arduino version 1.8 or higher. If this is
your first time using Arduino, you can install it by following our Installing the Arduino IDE tutorial. Otherwise,
please make sure to install (or update to) the latest version of Arduino and verify that you are connected to the
internet to download the LilyPad USB Plus software add-ons.
Now that you’ve explored the board’s features, it’s time to upload some code! When you first install Arduino, it knows
how to program a number of “standard” Arduino-compatible boards. Since the LilyPad USB Plus is a newer LilyPad
microcontroller, you will need to manually add it to this list by following the steps below. You’ll only have to do this
once to add the board to Arduino.
Note for Linux Users: If you are installing the LilyPad ProtoSnap Plus in Linux, this document has some
specific
notes:https://github.com/sparkfun/LilyPad_ProtoSnap_Plus/blob/master/Documentation/LinuxInstallation.md.
1. Add SparkFun Boards to Arduino’s Preferences
Start the Arduino IDE software (version 1.8 or higher) and open the Preferences window by
choosing File > Preferences from the menu.
Now copy the below text and paste it into the “Additional Boards Manager URLs” text box:
https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/pac
kage_sparkfun_index.json

No room? If there is already a URL in the box, click the button to the right of the box. This will open a window
allowing you to paste the URL onto a new line.
When you’re done, click the “OK” button.
2. Install SparkFun AVR Boards
Next, you’ll add the LilyPad USB Plus through Arduino’s Boards Manager Menu. Open the Boards Manager by
choosing Tools > Board > Boards Manager…(The Boards Manager option is at the very top of the list of boards;
you may need to scroll up to see it.)

https://learn.sparkfun.com/tutorials/lilypad-protosnap-plus-hookup-guide?_ga=2.234157401.659504291.1516640116-204410570.1509632255 10/23
When the Boards Manager window opens, it will present a long list of options. Type “sparkfun” (without quotes) into
the “Filter your search” box at the top of the window. This will shrink the list down to SparkFun’s options.
You should see several entries. Look for the one labeled SparkFun AVR Boards by SparkFun Electronics.
Troubleshooting: If you don't see a SparkFun entry, it may mean that the URL you pasted into the Additional
Boards Manager section of Arduino's preferences did not load correctly in Step #1, or you're not connected to
the internet. Double check that the entire link was copied into the Additional Boards Manager URLs, and that
you're connected to the internet. You might also try closing and restarting the Arduino software to refresh the
preferences.
Click anywhere in the SparkFun AVR Boards box. A version number and an “Install” button will appear. Click the
install button. This will download and install the extension. If you have already installed the SparkFun AVR Boards
