============================================================================
A Tutorial on programming your PC /Laptop Virtual serial port (VCP) to communicate with an Arduino or a Microcontroller System using Python and Pyserial Library.

Accessing the Serial port is one thing any embedded engineers must know.
This tutorial teaches you the following things.

1) How to install Python on Your system
2) How to install PySerial using PIP Package Manager
3) How to Open the Serial Port (VCP) using PySerial Library
4) How to Configure Baud Rate ,No of data bits ,Parity ,No of Stop Bits of your Serial Port using PySerial Module and Python
5) How to Transmit serial data using PySerial and Python to Arduino from PC
6) How to Receive serial data using PySerial and Python from Arduino and Display it on Console.
7) How to Close the Serial Port in Python
8) How to transmit and receive (echo) a character send from Arduino using Python

This is wonderful! The only tutorial on YouTube that shows the whole process!
Thank you.

I like how calm your voice is btw! Most channels try to be too active and shout!

I almost never subscribe but subscribed to you.

Cheers.

I was trying to send 130 integer data from Python to Arduino for days. I had used just serial.Serial('COM4', 9600) . I had not used as you used. Now, I did the same thing as you and it worked.

[omodolapojaiyesinmi]

good work expecting pserial exception video soon expecially how to clear the memory after serial communication without ending serial which makes the arduino or esp32 respond faster

[rahul_sreedharan]

Hey nice tutorial, well done.it was quite helpful

[Khalid_Vau]

could not open port 'COM2': PermissionError(13, 'Access is denied.', None, 5)



please help me !!! i've watched 7 tutorials on it . but my code is giving this error !

[nguyenninh]

can I send data from arduino to py and vice versa in a same program ? Like datas from sensors

[pranav]

I can't find the cs file generated

[ahmadhafiz]

I have this error

Traceback (most recent call last):
File 26april buzzer.py", line 39, in <module>
arduino = serial.Serial(arduino_port, baud_rate, timeout=1)
AttributeError: module 'serial' has no attribute 'Serial'

[pekorabestgirl]

Hello, I have a question.
Since I don't have Arduino uno, is it possible if I just connect two PC with usb to RS-232 converter and have 1 pc send signal to the other using serial.write() and use serial.readline() to receive?

[MTos-lo]

How do we send sensor data from Arduino to the pc directly?

[mashrishi]

Great tutorial. Is it possible to listen to the a COM port continuously and capture a string upon arrival with out over loading the winXP PC? I suppose using some kind of COM wake up on interrupt or similar concept.

[vthelagan]

can we do the same with esp32 wroom 32 board

[aboubakarmohamadou]

Thank you, but i have some issues : SerialException: could not open port 'COM6': PermissionError(13, 'Accès refusé.', None, 5)
No specific suggestions for this error (yet).

[balakishore]

I canot find a port section in device manager

[muzamilabbaskhakwani]

No pyvenv.cfg file

this appears if I check my python version. please help
