Amazing tutorial, thanks Stacey! For those who have tried this recently and ran into problems like me, this tutorial was created with version 4.0 of serialport package, they seemed to have changed things in the 5.0 release. So use this command line instead: npm install serialport@^4.0.0 --save
Awesome video! Love this stuff, I just wanted to see shotly what it was all about in order to know if it was what I was looking for and you provided just that! Thanks
For some reaseon, *parser:serialport.parsers.readline(' ')* doesn't work. If I type * parser: new serialport.parsers.Readline(' ') *, it does somewhat work, but it gives out the imput in hex code. Apart from that, the code is the same. Does anyone know what the problem might be?
For newbies like me who tried this and had some errors.. here is the code that worked for me (Date: 03/26/2020) const serialport = require("serialport"); const SerialPort = serialport.SerialPort; const portName = process.argv[2]; const myPort = new serialport(portName,{ baudRate:9600, parser: new serialport.parsers.Readline(" ") }) myPort.on('open',onOpen); myPort.on('data',onData); function onOpen(){ console.log("Open Connection"); } function onData(data){ console.log("on Data " + data); } /// I am an absolute newbie so I cannot tell you why the code needed to be altered. My guess is the serial port version has changed.
Thank you, it worked, pretty much. Did you do any changes besides *parser: new serialport.parsers.Readline(" ")* ? because I could swear I had it like that before and it didn't work.
How do you pass in a command to your arduino using serialport nodejs?? For example .. how to run a example.sh script file on your arduino using nodejs?
The way I did it in a project I did a while back is by sending back the letter "a" using *myPort.write('a ')* in the js code. Could be any letter or string, doesn't have to be an "a". Reading that string on the Arduino is a bit tricky and I'm still not sure how I did it exactly, but here's the code *char out[1];* *Serial.readBytes(out, 1);* *if(out[0]=='a'){* your code *}* so once it recieves the letter, it does whatever code it is supposed to do. You don't really pass a command through the serialport in that case, only a signal that triggers whatever code you have on your arduino. Might be a bit late for you, but maybe it helps other people a little bit.
i have a error here parser:serialport.parsers.readline(" ") TypeError: Cannot read property 'parsers' of undefined but i cant solve it i dont understan what im doing worst but Congrats 4 amazing tutorial, thanks Stacey!

THIS WAS SOO HELPFUL!! thank you!!
Great! Now I need to send this prompted data to a Database or something that allows me to do it. Any clues? All the best!!
How do write data to Arduino?
thanks Stacey Mulcahy . this is what im looking for :)
Simply Marvelous!
great! is it possible to send from node to arduino ?, any idea how to achieve that?

Hi, thanks for this.
I am trying this with Arduino Yun.
Could you please let me know how I can use network port to communicate with ardiono over wifi?
Hi Miss Stacey, may we ask how to display serial outpur "Stacey" on an HTML with Node.js please
Is the module still alive/available today?

Weren't you my prof one year?
Hahaha
Thanks for the tutorial.

Can you tell me how you installed the module?

Great and concise video, but please format the JS code better, it's driving me crazy!
Great job!
Thanks, it worked (:
this does not work anymore
Thank you so much
this beauty itself compared with the com port in WinAPI;).
It doesn't let me have 2 connections to the same port, how do I fix that?
Video is not clear :(
Please read the tutorial here is the answer of many troubles! node-serialport.github.io/utilities/ReadLineParser.html
