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?
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
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!
Absolutely. Each Arduino is just a serial port on your Pi and if you add usb hubs, you can add something like 127 arduinos per USB port. This video shows how to communicate from the pi to the arduino ...which is the same technique you use to go from one arduino, through the pi, to the other arduino. th-cam.com/video/eqO_aH9Us28/w-d-xo.html

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
Awesome! Glad you found it helpful!
Easy to follow, even for a beginner. Thank you so much!
You are very welcome! Glad it helped!
That was Fan-freaky-tastic!
Awesome! Glad it helped!
Nice video for a starter. Thanks a lot
Most welcome!
That's a REALLY good content!!!! Thank you!!
You're very welcome!
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.
Awesome thank you!
This works fine, did you ever tried to get alle inputs and outputs from the ardiono in node red?
Yeah. It's basically the same process. You just have to make sure you're telling node red which input is sending what.
That was helpful to me! Thanks
Glad it helped!
Life saver!

Hmm.Are you on windows?
will the raspberry pi port provide sufficient power to the arduino if I start attaching sensors into it?
Yes for sensors. If you ran a bunch of relays or solenoids, maybe not, but normally it's not a problem.

oh wait, I already solve the problem
Glad you got it sorted!!!
@@AnotherMaker hehehe thanks for the tutorial💕
in the available ports I can't find the USB one. what i have to do? the arduino is Arduino Mega
It may not actually say USB. Have you tried the others as anyway?
Another Maker ohhhh thank you! Now it seems it has connected! Later I’ll try it
Thanks!
Glad it was helpful and thank you for the generous donation!

@@AnotherMaker Thank you for replying so quickly!! You've been a great help!
How can i operate the nodered remotely using vnc?
Most Pi OS' have vnc built in. You just need to enable it in the settings, then I use tightvnc to view it from windows.
Hey sir, I have some problems, may you help me?
How can I help?
