Cylon.js For LightBlue Bean

Cylon.js (http://cylonjs.com) is a JavaScript framework for robotics, physical computing, and the Internet of Things.

This module provides an adaptor and driver for the LightBlue Bean from Punch Through Design. The implementation uses the bean-serial node module from @monteslu, which in turn uses the ble-bean node module from @jacobrosenthal. Thank you both very much!

How to Install

Install the module with:

$ npm install cylon cylon-bean

Installing Firmata Firmware On Your LightBlue Bean

To use the complete functionality of your Bean, you will need to install the Firmata sketch on the Bean itself using the Bean loader. Install it, by following the instructions for your operating system on the LightBlue site:

• For OSX go to http://punchthrough.com/bean/getting-started-osx/
• For Windows 8.1+ go to http://punchthrough.com/bean/getting-started-windows/
• Linux is not yet supported for LightBlue Bean firmware updates. You can connect to Bean as a client from Linux, just not update the firmware (yet).

How to Use

You can connect to the built-in LED, accelerometer, and thermometer of the Bean, by using the bean driver:

var Cylon = require("cylon");

Cylon.robot({
  connections: {
    bean: { adaptor: "bean" }
  },

  devices: {
    bean: { driver: "bean" }
  },

  work: function(my) {
    every((1).second(), function(){
    	var r = Math.floor(Math.random() * 255);
    	var g = Math.floor(Math.random() * 255);
    	var b = Math.floor(Math.random() * 255);
    	my.bean.setLed(r, g, b);
    });
  }
}).start();

You can also connect to GPIO and i2c devices using the bean adaptor:

var Cylon = require("cylon");

Cylon.robot({
  connections: {
    bean: { adaptor: "bean" }
  },

  devices: {
    led: { driver: "led", pin: 5 }
  },

  work: function(my) {
    every((1).second(), my.led.toggle);
  }
}).start();

How to Connect

The LightBlue Bean is a Bluetooth LE device. By default you will connect to the first Bean, for example:

Cylon.robot({
  connections: {
    bean: { adaptor: "bean" }
  }
...

If you want to connect to a specific Bean, use the beanName parameter like this:

Cylon.robot({
  connections: {
    bean: { adaptor: "bean", beanName: "mybean" }
  }
...
