Hello, your video is excellent. I have a question. If I wanted to read two ports at the same time using pyserial, how would that be? Could you help me? Thanks.

import serial line 1, in <module> import serial ModuleNotFoundError: No module named 'serial' ~ I've installed pyserial in everyway possible and even tried unistalling and installing it again. I tried using sudo to put it in dev mode to get it back working to only focus on the microcontroller. None of them worked and I still get the no module named serial error! what should I do?

Hello sir, May I ask if do you know how to fix the " Access is Denied " problem? I've been dealing with it for the past 12 hours. Thank you in advance!

Why not use esp ?

I am trying to send a message to the IoT hub as well. I understood that the azure.iot.device.aio is for the async instance of IoT Hub Device client objects. However, if there is no internet connection, the device_client.send_message(data) will keep on retrying until the internet connection is restored which is a bit counter intuitive with the nature of its asynchronicity. Without internet connection, the device_client.send_message(data) becomes synchronous and will halt other operations. Is there a way to overcome this? I tried using threads but the issue persists.

Thank you !

Thank you !!! wonderful !! I can send data to my ardruino !!! You save my brain 🧠

Thank you so much!

Thank you very much for the tutorial.

hello ı have some question . I want to use in virtual serial ports how can ı make

how? I literally just get a syntax error

hello Avirup. Great video !!! Unfortunately, I copy/pasted your code, the only thing that I changed was the connection string and even like that it didn"t work :( The error message says: 34 "asyncio.run() cannot be called from a running event loop") Any idea ?

Hello SIr. I have watched your video. I have a problem related to python serial and barcode scanner. I have a USB Barcode Scanner and plug into my Ubuntu PC. The Scanner is work propperly, since when I used it, it will output the reuslt of barcode on every cursor i put (such as terminal, vscode, etc.) but the `received_string` variable is always empty. The script is not give any error. Do you have any idea? ``` import serial import time SerialObj = serial.Serial("/dev/ttyS0", 9600) time.sleep(3) SerialObj.timeout(3) print("Starting") while True: received_string = SerialObj.readline() print("Received: ", received_string) SerialObj.close() ``` I want to retrieve the data using Serial with the code, so the variable `received_string` will be assign with the value of the scanner data, but I always get `Received: b''`.

is the call ser.readline() a blocking call ? if so then how to do it without blocking the rest of the application ?

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

I like where you are going with this, could you turn your explanations into a project that we could follow along ie. a bmp280 sensor connected to a pi pico plugged into a pc, reading the data into file, then shipping the data to the cloud etc....

Superb! Thanks man!

Clearly understood... thankyou

theri level ... .Easy but superbly explained .

Thanks Bro.... this much clearly no one told me.... superbly understood

simple but concise!! thank u sir
