Johnny Five : The JavaScript Robotics & IoT Platform

What is Johnny Five ?

Johnny-Five is an Open Source, Firmata Protocol based, IoT and Robotics programming framework, developed at Bocoup in 2012, Johnny-Five  is maintained by a community of passionate software developers and hardware engineers. Over 75 developers have made contributions towards building a robust, extensible and composable ecosystem. Johnny-Five programs can be written for Arduino (all models), Electric Imp, Beagle Bone, Intel Galileo & Edison, Linino One, Pinoccio, pcDuino3, Raspberry Pi, Particle/Spark Core & Photon, Tessel 2, TI Launchpad and more!

Just interested in learning and building awesome things? You might want to start with the official Johnny-Five website. The website combines content from this repo, the wiki, tutorials from the Bocoup blog and several third-party websites into a single, easily-discoverable source:

  • If you want to find the API documentation, that’s right here.
  • Need to figure out what platform to use for a project? We put that stuff here.
  • Need inspiration for your next NodeBot? Check out the examples.
  • Want to stay up-to-date with projects in the community? Check this out.

Johnny-Five does not attempt to provide “all the things”, but instead focuses on delivering robust, reality tested, highly composable APIs that behave consistently across all supported hardware platforms. Johnny-Five wants to be a baseline control kit for hardware projects, allowing you the freedom to build, grow and experiment with diverse JavaScript libraries of your own choice. Johnny-Five couples comfortably with:

How To Use | Setup and Assemble Arduino

  • Download Arduino IDE
  • Plug in your Arduino or Arduino compatible microcontroller via USB
  • Open the Arduino IDE, select: File > Examples > Firmata > StandardFirmataPlus
    • StandardFirmataPlus is available in Firmata v2.5.0 or greater
  • Click the “Upload” button.

If the upload was successful, the board is now prepared and you can close the Arduino IDE. For non-Arduino projects, each IO Plugin’s repo will provide its own platform specific setup instructions. Visit This Post : Using Node js and Arduino with LED Blinking Program

Installation :

Source Code:

git clone git://github.com/rwaldron/johnny-five.git && cd johnny-five

npm install

npm package:

Install the module with:

npm install johnny-five

A Sample Hello World! Program

var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  // Create a standard `led` component instance
  var led = new five.Led(13);

  // "blink" the led in 500ms
  // on-off phase periods
  led.blink(500);
});

Platform Support

Johnny-Five has been tested with a variety of Arduino-compatible Boards. For non-Arduino based projects, platform-specific IO Plugins are available. IO Plugins allow Johnny-Five code to communicate with any hardware in whatever language that platform speaks!
