This is the first Node Red video that I have found that actually shows a beginner how it works and also explains how this is a practical starting point for further learning. Thank you so much for this, really appreciated.

You so beautifully and precisely showed how a physical sensor (the reed switch) can be monitored on a web page using Node Red. Many other tutorials on YT simply drone on endlessly about nodes and message payloads but that doesn't help beginners to actually understand how Node Red can integrate with the physical world. Keep up your great work.

Excellent, thank you. Really straightforward, clear, concise and easy to follow for a beginner. Now subscribed

Excellent videos and exactly what I've been looking for! I am eagerly awaiting the Node-Red w/ MQTT tutorial. Thanks for your great work!

This is the best simple tutorial ever!!

thank you, this was extremely helpful. i finally have a dashboard to put live sensor data on!

you rock dude. Helped me out a lot with my IoT assignment. Much love

Thanks a lot, exactly what I needed!

Sir,U r explanation is just great make video more please😫🙏🙏💓

Very informative and simple, Love it, Thank you!

Thank you. All the learning out there assumes a lot on the learners part of either knowing C++ OR node red....i understand neither bt want to get started. The community really needs to figure that part out. If people want to learn but know nothing...there is little tget them started. Stuff like your tutorial here is REALLY needed. Explain it all amd assume the learner knows nothing. If people are advanced....skip through the video.

Amazing video ! .. using this concept for a hackathon :)

Muchisimas gracias por compartir. Fue demasiado útil y muy facil de entender tu explicación.

Thanks a lot for your great video. Is there any way to link Node Red to the Arduino through WiFi

GREAT WORK....♥️ from INDIA

Big thumbs up! Excellent video

You have helped me a lot, thanks :)

Great video again, well done. I hope you will show some wireless examples with MQTT and node red :-)

Thanks! Great explanation!!

Hello, now ist this also interest for me. But how i can send a one Wire bus to Node Red. I have 18 temperatursensors one one Pin an i will See this in Node Red. Can i also Switch other pins for functions?

Wonderful Video. Like your English.

There is an easier way. First you install only Arduino FIRMATA on the ARDUINO. Then you install the Arduino NODE in Node-RED. An easier way to talk to arduino than the Serial node ;) In this way you will be able to talk to ALL of the pins of the Arduino, without the need to make a large sketches, everything will be manageble from Node-RED.

Excellent video! Thanks

Hello, I want to set the parameters of an industrial drive using a node through RS485 serial communication. In this project, I need to use the hex codes of an industrial drive and control the drive using the hex codes. Can you help me with this project with node-red-node-serialport?

so nice thankyou sir

outside of playing around/learning you will never build a system that has just one sensor so say you have Arduinos/sensors in multiple locations, how will you read all the data into node red at once, I would think you would likely setup node red on a raspberry pie or something so only have 1-4 usb ports to get serial from, there must be a better way?

Very nice! Thank you!!

On the 2nd Tab you have the dashboard open, how do you access the web page (How do i get to this screen (address) Sorry i hope this is not a stupid question

Thanks a lot for your great videos! I have a very basic question. I have created a Node Red Dashboard on my Raspberry Pi. I connect my Raspberry to Internet using Huawei 4G to wifi router. I would like to acces to my Node red Dashboard from any pc in the world over Internet. Do you have any suggestion how to do this? Thanks a lot a again!

i have some error "[serialconfig:8bd3c8c47c237574] serial port COM2 error: Error: Opening COM2: Access denied" can i fix that?

Can u teach timemer on node-red with esp32

Love these videos. Is it possible to achieve the same thing using a wireless connection to the Ardunio board? It would be difficult to run USB cables from the control room into the escape room and into every Ardunio board.

For some reason I do not have a [Home] Default group to select. So I do what I think is right and add a group, it now displays as [Home] [Home] Default, so I did not add it correctly.....

Great video _ much appreciated _ one wrinkle for me _ to get serial button in dashboard _ I had to install Visual Studio Community Edition (I already had Visual Studio Code installed.)

which site do i need to enter in the browser to see the dashboard?

How do you access the dashboard tab?

Hi Alistair, hope it's ok to ask a Node Red newb question. Can it manage video files? What I want to do is trigger a video to play based on an arduino pin reading, and this would be perfect if it's supported in Node Red.

How to activate arduino sketch only when prompted in node red and not when connected to serial port after my timer runs down to zero? Pls advise. Thx

Thx for this video

Hello.! Thanks for the awesome video, but can we use Arduino In node to get input, rather than serial in ??

11 Feb 08:26:36 - [info] Starting flows 11 Feb 08:26:36 - [info] Started flows 11 Feb 08:26:36 - [error] [serialconfig:11d6dad84156b4a6] serial port COM3 error: Error: Opening COM3: Access denied its showing me this error when i tried to connect with node red, but my arduino is connected to the system with the same port. How can I solve this problem

Sir how to show text word as a out put in dashboard

ty for sharing bro

I want to send raspberry pi data to Arduino. suppose I have integer value '512' on raspberry pi node-red and I want to send that on Arduino so how can I do that?

Can you write an Arduino code in Node-red instead of using the Arduino IDE?

Its Great video....Thanks bro...can you share guidance about how to read this value from arduino when it is connected to laptop port say com3 and nodered is running on raspberry pi means on different workstation and I am working on my laptop and accessing nodered there. Thanks

Hey! I don’t have any options in the TEXT node / group … Why?

hey sir do you know how to this but without using any usb wire at all??

Sir , whatever I do I see my serial port is not connected to node red.could you help me out of this

Very good

You failed to mention where node red is running, I assume its on your pc.

Is this can work with Arduino analog input ??

14th line of code Serial.print*n (currentState); Is that a *1?

Can you do the code in NR with some function nodes?

error , i have no group ...

So where is Node-red installed then???

Can you connect same circuit to raspberry pi ?? I mean Arduino connected to raspberry pi

Nice :)

error "please add some ui nodes to your flow and redeploy"

Thanks for the video. it is very rare and very explanatory. actually i am thinking of hosting rednode and then i can connect via port forwarding. But how to send this sensor data to the rednode IoT center : self hosted). it will be very helpful if you can make a tutorial about it. thanks in advance

I seem to be having a nightmare trying to install the node-red-serial palette. It keeps failing to install and I don't really understand anything on the error log! The only thing that makes any sense to me is this bit: 2020-08-26T14:52:05.002Z [err] gyp ERR! find VS You need to install the latest version of Visual Studio 2020-08-26T14:52:05.002Z [err] gyp ERR! find VS including the "Desktop development with C++" workload. 2020-08-26T14:52:05.002Z [err] gyp ERR! find VS For more information consult the documentation at: 2020-08-26T14:52:05.002Z [err] gyp ERR! find VS github.com/nodejs/node-gyp#on-windows But I have installed Visual Studio (eventually), after installing python which it seemed to be missing first. I've tried reading through the github page mentioned above, but again just don't really understand any of it. Should I have to be installing all this stuff or am I missing something? The real question I guess is should I even bother trying to get this to work? I was trying to work through all your tutorials so I could learn stuff step by step, but my end goal is to set up props and control software for three escape rooms, so will likely end up using ethernet or wifi connections anyway. Any help or advice would be much appreciated!

Frankly, this is what pisses me off about Arduino, its meant to be accessible but they use a hard language to learn, I learnt Delphi C back in the 1990's and it was horrible language to use and you have to do things that should be automatic like memory and housekeeping. Until arduino stop using C only, I won't ever by one.
