Hello, is it possible to do this project on the Raspberry Pi 0W? thanks

Hello. Is the digital output a positive or negative one?

is this converter RS485 to RS232 ?

Thank you very much. I have been working on controlling a VFD from a PLC and I can monitor my VFD values. Just a note, I had to swap the A and B 485 connections.

Can you show us how to do this in an Arduino board (UNO)

Thank you, this helped a lot👍

Hello, I tested it and the temperature only shows "Sending: -127.00" The module is ok. I tested the Lora and the DS18B20 separately and it works fine. However, the complete code keeps giving this. I've changed the libraries and tested other codes and nothing.

danke - dein Tipp hat mein Problem gelöst!

Hi. Does anybody knows if those libraries and configurations are still working in 2024?

Plz your email

I NEED YOUR EMAIL PLZ

Im getting a Data lenght error, has anyone encountered this?

works like a charm, thanks for the video, frm the Dominican Republic

worked today 24.04.2024, thank you mister

could you please help me! i am not using raspberry, i work with pycharm and cmd! i have the same problem -lost connexion- but with roles.findOne()

Hay sir do you have a contact that I can contact you directly ?

Your contact please

source code please

Getting the error "ModuleNotFoundError: No module named 'umodbus' even though I installed it like he showed. Any advice? Don't get the same open options you do in the video.

Hi sir, instead of reading registers through modbus, can I use the Arduino to write registers on for example a PLC? Would you be able to provide me an example program?

how can i made the same proyect but with a ESP32?

Sir how to write the register

How can you access the ui from different devices?

Hello I did everything like you except that the current Python version is 3.11.2-1. However, I get -26 as a value with a sensor and 0 without a sensor.

the link is broken sir, may you send me the code. thanks

Thank you, I learned software serial configuration in your practice.

Can you configure node red to run at start when raspberrypi start-up?

Hi

Can you explain why you used 4 relay module and not 2relay module? Thank you

"Is it possible to communicate one Raspberry Pi with this module connected to two ESP32 Lora Heltec V2? The Heltec modules use the same type of module. Do you think this communication setup is feasible?"

Hi thanks for the video. Quite helpful. How will the connections change for a PNP sensor? I am using it with a raspberry Pi4 and calculating the time difference between each count to get the cycle time for a band saw cutting machine

ImportError: no module named 'logging'

The RPi GPIO are not 5v tolerant. Wouldn't a voltage divider be necessary here on both the encoder A/B?

hey i want to find the time period of an object passing thorugh the proximity sensor.. how do i do it

i did almost the same project but i use dht11. When you start the code to the raspberry pi how does the arduino send u the vaules, without compiling in the arduino?

nice

Whats data[16] for?

thank you so much my friend! Exactly what i was looking for!

chào anh. mình kết nối cảm biến lưu lượng nước và màn hình oled 0.96 inch, nhưng làm theo hướng dẫn thì báo là không thể kết nối với màn hình. anh có thể cho mình số zalo để mình hỏi thêm chút cho tiện đc không. cảm ơn anh.

Is this process common for all type of RPi boards ? (RPi nano, 3,3B,4B etc.)

Hi Sir, Can you refine the code and recreate the video please ? it is Very useful but when we run your code one by one error is appearing dont know how to resolve those errors with limited knowledge so I request you to share new code or something whichcan help us to make it work

Good tutorial, easy to follow

grazie mille

good explaination.. thanks bro

Can the LCD display celcius symbol ° ?

Bonjour, pour faire suite a mon dernier commentaire, j'ai put remarquer que je n'utiliser pas le bon noeud.Celui ci fonctionne parfaitement : node-red-contrib-pcf8574-lcd même pour mon LCD 2004

Bonjour ,Serait il possible de connaitre le noeud de l'ecran.J'ai pour ma part un lcd 2004A et j'ai l'erreur suivante :23/09/2023 01:50:55noeud: function 1 function : (error) "ReferenceError: nmsg is not defined (line 2, col 1)" Merci de votre aide

THANK YOU FOR THIS - Most of the libraries out there are all python2 and I want to stick with 3. I am also JUST starting out, so this helps a bunch! - Im working on converting this to Fahrenheit - LOL FOUND it in your GetMAX6675 file.
