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.

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.

The best i could recomend you, is to use the Node-MCU + TASMOTA firmware on it. Then install mosquitto server on the machine which is running Node-RED, and then you will be able to talk to the MCU from Node-RED via MQTT. Its really easy.

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.

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?

Oh yes - there's many ways to connect! Wired ethernet, wireless, USB, DMX, ModBus, CanBus, MQTT or HTTP, JSON, CSV, binary, or simple text payloads.... they'll all be coming soon - I just wanted to get this example out first because I think it's the simplest to understand - people are already familiar with using the USB cable to upload code to the Arduino, and I've already used Serial.print many times to send data back from the Arduino to the Serial Monitor. The only difference in this example is that I'm picking up that value in Node-RED rather than in the Arduino IDE.

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!

So are you trying to install the node by going to the Manage Palette option from the dashboard? I've never seen that error before - are you using a Windows PC and, if so, are you logged on as a user with admin privileges?

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.
