johnny-five not working

[Sarthak-Arya]

const { Board, Led } = require("johnny-five");
const board = new Board({port:"COM3"});

board.on("ready", () => {

  // Create a standard `led` component instance
  const led = new Led(13);
  this.repl.inject({
    led: led
  });
  // "blink" the led in 500ms
  // on-off phase periods
  led.blink(1000);
});

Above is my code

Here is the output is not showing anything I am using Windows 11 x64 bit system

Is it throwing an error like "cannot find module 'firmata' " ???

Or what's the result actually..

I don't think so, but I'm facing this error, is there a solution?, I tried install firmata package but always fails: npm ERR

Error: Cannot find module 'firmata'

It's almost a year later and I'm having the same issue with no ability to find a solution.

npm i firmata

const { Board, Led } = require("johnny-five");
const board = new Board({port:"COM3"});

board.on("ready", () => {

  // Create a standard `led` component instance
  const led = new Led(13);
  this.repl.inject({
    led: led
  });
  // "blink" the led in 500ms

  led.blink(1000);

Your code shouldn't output anything. It should blink the default led on your board (of course if it is really on port 'COM3')

[tbaltrushaitis]

Also I'm not sure if this would represent your board because of () => {}

npm i firmata

This wouldn't fix it, and there would be a laundry list of problems that would follow. I have however figured out the root cause for this issue and others People trying to run Johnny-five with a fresh install of Windows 10 or 11 and windows build tools 2022 CANNOT install johnny-five with "npm install" I have found that you need node version 13.14.0 or 14.17.0 (if you tried installing johnny-five with a newer version you need to delete your node_modules folder then change versions of node with nvm-windows) then install VS Build Tools 2019 (VS Build Tools 2022 will not work!) with C++ development.

After this johnny-five can install successfully with npm install. (Antivirus may also need turned off, run from powershell with administrator privileges too)

VS Build Tools 2019 Download: https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16&src=myvs&utm_medium=microsoft&utm_source=my.visualstudio.com&utm_campaign=download&utm_content=vs+buildtools+2019

Remember also to turn off any Bluetooth connection, make sure that the package.json has into script: "firmata": "firmata-party uno --debug" and npm run firmata. And then node index.js
