Qwik & Arduino with Johnny Five
Some times ago I have played with johnny-five, a JavaScript Robotics & IoT platform. In short words, we can communicate with our Arduino or Raspberry by using JavaScript with a very friendly syntax.

Dockerize Javascript IOT Applications
The library Johnny-Five is a Javascript library that allows you to control Arduino and other microcontrollers using Javascript. It is very easy to use and it has a lot of examples that you can use to learn how to use it.

Is there a differnece if I program the Arduino using NodeJS instead of it language c/c++
+Here is the platform used to program the board http://johnny-five.io/
- Arduino to PC Serial Protocol Library

From Wi-Fi to Li-Fi, sending data via light using Arduino and JavaScript
I decided to use the Johnny-Five JavaScript framework for this. After installing it , I started by declaring a few variables and instantiating the transmitter board.

Guide please🙏i will really mean a lot.
IOT is the internet of things. That loosely means - interconnected devices that aren't your standard "computer." You can totally do that with JS and a little computer like an Arduino. You can use https://johnny-five.io/ or something... but I'm talking about - a year from now -

help - Cannot figure out why I keep getting SyntaxError: Unexpected token {
here it the project's github: https://github.com/rwaldron/johnny-five

JS Library for controlling devices with cameras
Johnny Five seems like a neat project for that bit. What I'm trying to find is a library for using the camera bit. Sorry if my original question wasn't specific enough. I'll try to clarify here.

Anybody build / programmed LEDs using Node?

Firmata on ESP32 (WROOM)
I am trying to put Firmata on ESP32 and connect it to the johnny-five lib (or any other JS client). I managed to put official Firmata and other forks related to ESP32, but it doesn't work (build+upload succeed), but I'm getting "ready" from the device.

Guru Meditation Error if more than 2 Pins/ 2 controller are used with filehandling
I used the examples from here https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples
- FastLED's newest feature - HD mode for the APA102/SK9822/Dotstar LEDS
- High Bit Depth Gamma Correction Algorithm for APA102/Dotstar LEDs
- Is there an alternative to using two WS2811 ics to control RGBW channels [first image], and are there any adjustments needed for the current regulator circuit [second image] ?
- Frames getting stuck with ESP32 and 16 by 16 LED Matrix
- changing brightness of the individual led's?
- Arduino Due SPI to control LED strip(s)
- Powering 300 LEDs w/ battery
- led_sysdefs_avr.h error

Multiple RGB outputs
Sweet. Then pretty much any arduino or other microcontroller would take care of what you need. The strips only take one output pin plus power and ground so just about everything will work for driving them. They act like a long shift register so the single pin is all that's needed to load the full strip with whatever patterns you want regardless of the length. You just have to tell it how many LEDs there are in total is all. Check out the FastLED library. You can learn more about it there and/or install the library in the IDE by pressing "ctrl shift I" for windows or "command shift I" for mac and search for it in the upper search area and install it right there. It comes with working examples too so all you would have to do is install the library, load one of the new example sketches that came with it, and probably edit the example to change the NUM_LEDS count to match what you're working with.
