JavaScript Robotics and IoT programming framework, developed at Bocoup. Based on Arduino Firmata Protocol

Node-isassemble Johnny-Five

Build Status Gitter

Johnny-Five is an Open Source, Firmata Protocol based, IoT and Robotics programming framework, developed at Bocoup. Johnny-Five programs can be written for Arduino (all models), Electric Imp, Beagle Bone, Intel Galileo & Edison, Linino One, Pinoccio, pcDuino3, Raspberry Pi, Spark Core, TI Launchpad and more!

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:

...And that's only a few of the many explorable possibilities. Check out these exciting projects: node-pulsesensor, footballbot-workshop-ui, nodebotui, dublin-disco, node-slot-car-bot, servo-calibrator, node-ardx, nodebot-workshop, phone-home, purple-unicorn, webduino, leapduino, lasercat-workshop, simplesense, five-redbot, robotnik, the-blender

Supported Hardware

Johnny-Five has been tested on a variety of Arduino-compatible Boards.

For non-Arduino based projects, a number of platform-specific IO Plugins are available. IO Plugins allow Johnny-Five code to communicate with any non-Arduino based hardware in whatever language that platforms speaks!


Documentation for the Johnny-Five API can be found here and example programs here.

Here is a list of prerequisites for Linux, OSX or Windows.

Check out the bluetooth guide if you want to remotely control your robot.

Setup and Assemble Arduino

  • Recommended Starting Kit: Sparkfun Inventor's Kit
  • Download Arduino IDE
  • Plug in your Arduino or Arduino compatible microcontroller via USB
  • Open the Arduino IDE, select: File > Examples > Firmata > StandardFirmata
  • 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.

Hey you, here's Johnny!

Source Code:

git clone git:// && cd johnny-five

npm install

npm package:

Install the module with:

npm install johnny-five

Johnny-Five is...

var five = require("johnny-five"),
    // or "./lib/johnny-five" when running from the source
    board = new five.Board();

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

  // Create an Led on pin 13 and strobe it on/off
  // Optionally set the speed; defaults to 100ms
  (new five.Led(13)).strobe();


Watch it here!

Note: Node will crash if you try to run johnny-five in the node REPL, but board instances will create their own contextual REPL. Put your script in a file.
