Use a Raspberry Pi to power and parse data from an Arduino (EASY!)

(Links Below)
This super easy method allows you to connect any Arduino's usb cable directly to a Raspberry Pi (Or even a PC!) and grab the data. Note: I will cover installing Node-Red on a PC in a later video in this playlist.

Once you have it in node red, you can do anything from sending emails, UDP, TCP, or some really cool dashboards.

For Node-Red, hit the hamburger menu, click import, click clipboard. Paste the raw contents of the code above and click import.

Finally found it!! This is exactly what I was looking for. This is my kind of programming. I'll be going through your other tutorials. Thanks

Easy to follow, even for a beginner. Thank you so much!

This works fine, did you ever tried to get alle inputs and outputs from the ardiono in node red?

Nice video for a starter. Thanks a lot

That's a REALLY good content!!!! Thank you!!

How can i operate the nodered remotely using vnc?

will the raspberry pi port provide sufficient power to the arduino if I start attaching sensors into it?

Hello my friend. Thank you so much man. I subscribed already and will be sharing your link on my Facebook page. Thank you for sharing this.

I have followed this tuition and my Arduino is sending the messages as i can connect the Arduino to a pc and use the serial monitor with the correct baud rate and see the three messages. However when connect to the pi and set up the com port the serial node shows as connected but when i monitor the debug i get nothing. If i disconnect the arduino the debug shows a message port not found. Any advise?

Thank you so much for this! Liked and subbed!

How do I do go about adding multiple arduinos? Is it possible to affect one arduino based on the data of another arduino? For example: Arduino1 controls a pump, Arduiono2 controls a scale. Arduino1 pumps water until a certain amount/weight. Arduino2 is watching the weight and once the correct weight is reach, it will now tell Arduino1 to shut off. Is this possible with a raspberry pi as the master? Thank you! I don't expect a full detailed answer, but if you could guide me in the right direction and I could take it from there!

in the available ports I can't find the USB one. what i have to do? the arduino is Arduino Mega

[busraakargol]

Hey sir, I have some problems, may you help me?

[mauliadianti]

hai, nice tutorial. I have done the same, but I have a problem, when serial in created, and then I press deploy, it shows "not connected" and the debug message show "serial port /dev/ttyUSB0 error: Error: Error Resource temporarily unavailable Cannot lock port" does node-red really sensitive about apps that running in the background? if it doesn't do you have any other suggestions about my problem? thanks before
