Lilypad Plus Quick Start
Getting started
Use a Micro USB cable (WC7723) to connect the Lilypad Plus to your computer. You
should already have the Arduino IDE installed but if you don’t, you can download from
https://www.arduino.cc/en/Main/Software
This board uses an ATMEGA 32u4, which behaves similar to the Leonardo.

Additional Features
See below
Features
There’s a few included extras on this board which makes it a great way to try out many
things at once.
Connected Pin
Feature
Pin 17
10 x RGB LED lights*
Pin 5
Buzzer
Pin A4
Microphone
Pin 4 & Pin 19
Two separate Buttons (pulled low)
Pin A0
Temperature sensor
Pin A5

I2C
Accelerometer
To use the RGB LED Lights, you must install the “Adafruit Neopixel” library from the
Library manger, which can be found in the Tools menu.
Accelerometer
Code sample on next page for all devices other than the Accelerometer.
For an accelerometer example code, check out the File > Examples > Adafruit
Circuit Playground > accel_mouse example, and make sure the switch is set to (+)!
Code sample
This code uses Adafruit Neopixel library, version 1.3.2 or later.

Lilypad Plus Quick Start
Upload the following code and open the Serial Monitor with baud 9600
Change the board under Tools > Board to LilyPad Arduino USB
Change the port to be the port of your connected Lilypad Board.
