Esplora library

The Arduino Esplora has a set of functions for easily interfacing with the sensors and actuators mounted on the board. The functions are accessible through the Esplora class.

The library offers easy access to the data from the onboard sensors, and provides the ability to change the state of the outputs.

The sensors available on the board are:

  • 2-Axis analog joystick
  • center push-button of the joystick
  • 4 push-buttons
  • microphone
  • light sensor
  • temperature sensor
  • 3-axis accelerometer
  • 2 TinkerKit input connectors

The actuators available on the board are:

  • bright RGB (Red-Green-Blue) LED
  • piezo buzzer
  • 2 TinkerKit output connectors

For more information about the Esplora, vist the getting started guide and the hardware page.

NOTE: If you're using the Arduino IDE version 1.0.3 or earlier, you will need to download the latest version of this library, or get it from the Arduino gitHub repository.


The Esplora Beginners examples show the functionality of the inputs and outputs of the board. They are a good place to start experimenting with the Esplora's capabilities. The Expert examples are more detailed sketches that illustrate project ideas that utilize the board features in novel ways.



  • EsploraKart : Use the Esplora as a controller to play a kart racing game.
  • EsploraTable : Print the Esplora sensor information to a table format.
  • EsploraRemote : Connect the Esplora to Processing and control the outputs.
  • EsploraPong : Play Pong with the Esplora using Processing.
