Brain Coral Tutorial: Introduction

Version 16




    The Brain Coral is a stationary sensor platform that's part of Intel's Inside the Blue community project. During this tutorial, you will learn how to interact with the Linux side of the Intel Galileo, how to read sensor data using Node.js and the Galileo-io library, how to use RGB LEDs to visually represent sensor data, and how to use XBees to build wireless sensors. At the end of the tutorial we will give you the 3D model for you to print your own Brain Coral and house your Galileo.

    Parts list


    In this tutorial, our goal is to write a program using JavaScript to read incoming analog values from a distance sensor. At specific distances we set, the LED strip will play a unique sequence.


    We will be using the Internet of Things (IoT) SD card build. You can download it here: The Arduino IDE is not compatible with the IoT build.

    We’ll also be programming through the Linux side of the Galileo. To do so, you will need to telnet or SSH into the board. You can find your Galileo’s IP address using your network’s router software when you connect to the board. There are various ways to log into Galileo via the console. For more information, check out this post in the Intel® Community:


    We will be using Node.js, a server side JavaScript platform, to programmatically access Galileo’s General Purpose Input/Output (GPIO) pins.
