Johnny-Five is an Open Source, Firmata Protocol based, IoT and Robotics programming framework, developed by the Nodebots Community. 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!
Johnny-Five has grown from a passion project into a tool for inspiring learning and creativity for people of all ages, backgrounds, and from all across the world.

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:
The ubiquitous "Hello World" program of the microcontroller and SoC world is "blink an LED". The following code demonstrates how this is done using the Johnny-Five framework.
const{ Board, Led }=require("johnny-five");constboard=newBoard();board.on("ready",()=>{// Create an Led on pin 13constled=newLed(13);// Blink every half secondled.blink(500);});
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.
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!
To get you up and running quickly, we provide a variety of examples for using each Johnny-Five component. One thing we’re especially excited about is the extensive collection of Fritzing diagrams you’ll find throughout the site. A huge part of doing any Johnny-Five project is handling the actual hardware, and we’ve included these as part of the documentation because we realised that instructions on how to write code to control a servo are insufficient without instructions on how to connect a servo!
To interactively navigate the examples, visit the Johnny-Five examples page on the official website. If you want to link directly to the examples in this repo, you can use one of the following links.
There are presently 362 example programs with code and diagrams!
