Johnny-five: Running johnny five programm without laptop

[stefanvermaas]

Hi guys,

It might be a silly and dumb question, but is it also possible to upload to program to the arduino? So it can run without interference of a computer? I can't find any documentation about this.

Cheers.

There is no such thing :P

but is it also possible to upload to program to the arduino?

No, not the Arduino specifically, but yes you can run your Johnny-Five code directly on a BeagleBone, Raspberry PI, Linino One, Galileo or Edison (and others in progress).

Hi @rwaldron, why is not possible to do that with Arduino? I've seen Arduino working without any laptop or dependency.... Just the Arduino with something to control 🎮. It'd be really good to do that.

Thanks.

@sant123 it's certainly possible to use an Arduino without a connection to a laptop, but it's not possible to use Johnny-Five with an Arduino, since the JavaScript must run on some capable host (which the Arduino is not)

[sant123]

That sounds really sad @rwaldron, because after the program has been executed it should persist it and then it could be used without a laptop; like Arduino IDE.

By the way, thank you!

The Arduino doesn't host a JavaScript runtime. If you want to execute Johnny-Five code on a device, you'll need to use a platform that runs Linux and is capable of supporting Node.js. Otherwise, it's a host/client relationship that requires some kind of tether. It's not "sad", it's just the reality of supporting a variety of disparate hardware platforms.

@stefanvermaas To run JavaScript inside a hardware without an external computer I recommend to use Tessel 2.

Thanks for all the info! 😬

Hey there,

I am a bit confused. How is this project intended to be used if it can only be used with a PC attached to your hardware? Is this just for drafting things? How would you go und run your Arduino based hardware if you don't want to run a Laptop next to your IOT project?

Still I don't want to talk down on the project, I really appreciate it, I am just wondering how to use it.

Also, what about https://www.lowjs.org/ | https://github.com/neonious/lowjs ?

Johnny-Five is built on node.js, so it's not going to run on a humble Arduino. There are a number of single board computers that have GPIO on board and can run node.js and Johnny-Five (Raspberry Pi, Tessel 2, Beaglebone, etc) so you have a way to create a self-contained device with J5. If it has to be on a humble device like an Uno you will need a host PC connected via serial, Bluetooth, wi-fi or whatever.

lowjs looks interesting. I haven't spent any time with it so I can't comment on it.
