This is the best video I've found on this subject, Very clear breakdown of how the data is generated/transferred/handled. Thanks a lot!

This is an excellent series. Every module is well articulated. I learned a lot!

This is the best tutorial I've ever seen. Thumbs up.

This is an excellent presentation. Clear, concise and enough detail to make this extremely useful. The only comment I would have is that the rate at which you poll the arduino. From what I roughly calc...The actual conversion took 4.58 µs for 12 bits in single conversion mode with a 2 MHz ADC clock. If you read any faster than that you may get inconclusive data. Any comments?

Fantastic! Simple, clear, useful! Thanks a lot!

Sir， you said so clear that I can understand the knowledge, thank you wholeheartly.

Absolutely great tutorial! A lot of times, people posting "how to" videos skip the basics in their explanations. This leaves the beginner confused and unable to enjoy the steps associated with learning. I fully understood this tutorial, and I have hope that it will let me debug a related issue I'm having with my own application. Thanks for your work.

thanks for teaching and breaking it down into simple-to-understand terms. THANKS

Great Explanation! Keep up the good work! Thanks for sharing the amazing information!

smooth exercise, thanks for that.

I like your videos on the Python ardiuno ,I excited Ooooo

Great work, keeps it really simple, but it works, gave me just the start I was looking for. Running Python 3.8.3

This series on Pyserial is great and really helpful!

Best on the best

bro this was the best video that i found on this topic thx buddy. you explained it very well.

Very very useful information. And you explained in a clear way. 👍👍 Expecting more tutorials. Reading the same subject.

in my python version (3.7.6) i need to write ".decode('utf-8"')" instead .decode('ascii) . Great Video, thanks from Brazil for share the knowledge with us !

Thank you for posting! It was very helpful to see your coding with explanations such as how to use the decode command.

quick tip: close ur serial monitor before u start ur python code or else u would end up getting an error

Thnx this is the best tutorial I have come across

You are the best brother 👍

Thank you so much for this!! Very well explained 👍

The first video that is realy helpful, thak you so much!

te mereces una medalla de oro al conocimiento, thank you by your aport

This is cool, will be helpful for my data acquisition devices.

very good series

This is a very good explanation!!

Oh wow i didn't know this Library is commonly used in Arduino =). My thesis uses this library to communicate on Router =)

Thanks for making these videos.

Hello sir, can i use pyserial to collect and process data from power analyzer or this works only with arduino?......please answer my question

smooth exercise, thanks for it sir , awesome stuff and in best easy way

Very nice tutorial, Thank you!

Nice video. Thanks man!

Im very interesting about this

Nice and clear. Thank you! You have a sub.

The video is explained excellently .I have a doubt regarding the timeout value , will be it be delaying the whole data transmission. I am doing a data rate calculation. So my doubt is regarding the timeout parameter. It would be very helpful to if I get a reply

Thank you, this is really helpful to me!

Hi, Thanks for the video. Is there a video talking how to set up the hardware? Which pins did you use from the adruino to computer? Did you use a USB to serial (e.g. UART) adapter or just the USB cable to arduino? Thanks.

great job thanks

thanks man

Why it works sometime, and sometime not? Windows 10. Installed serial, but it complains that it is not installed. Once worked, then after changing parameters, does not work. Then again work... confusion.

why dont you need the following code in your void setup? pinMode(analogPin, INPUT); don't you have to tell it that it's an input pin?

Thanks a lot..!! best regads !!! great job,, SUSCRIBED.!

Thank you very much Sir, Its great video...

This video is great, easy to understeand and it works great. One question if someone can help me, is there a way to get the name of the connected port via script?

amazing. it works..

I love your videos i hope you will make more advance tutorials regarding uart communication as well. Just sub to the channel.Love you bro

thank you so much but i have a question can you use the arduino mega instead of the arduino

Many thanks this has helped a lot.

hey, why I get this error: serial.serialutil.SerialException: could not open port 'COM3': PermissionError(13, 'Access is denied.', None, 5)

Excellent tutorial!

I’m setting the timeout to 2 while creating the serial object. When I’m reading from serial port I’m checking wether data is present in input buffer by : if(obj.inWaiting>0) : If the data packets are interrupted it hangs in there.... I have given timeout value as 2 still it’s waiting indefinitely... why it’s not considering timeout value????

Amazing work

how do you set it up?

How to communication by Usb?

SerialException: could not open port 'COM3': PermissionError. Why?

Thanks, very good video.

Hello!....what if i need my python program to give instructions to arduino to do something(like....switch on a specific LED?)

is it possible to replace the integer with string?

how about receiving from python and reading it on arduino?

Hi Good tutorial !!! Please how we can making python send a float or int data to arduino and arduino get it (not str only )???

I love you bro

This is Great! Thank you

Hi sir, Is it possible to get the digital inputs and print them as the output using println?

What if the arduino puts out strings and not bytes? Is there a way to get python to output those strings?

so good and simple. Can you send me more info?

How can i use hc-12 with arduino using python language?.

hello, thanks for the video : good explanation , but for me when I execute the code it returns to me an error : No module named 'serial' ;;;; what should I do

KING!

Hi, I'm getting the following error: AttributeError: module 'serial' has no attribute 'Serial' The libraries serial and py serial are already installed. Could it be that you have Python 2.7 and i have 3.7. If so, how different would the code be? Regards,

Can you explain why we declared ser for serial.Serial()

it is a cool video! Thank you

when i try to run the code in python 3.7 idle why it is showing invalid syntax?

what about parity ,stop bit and number of bits?

Have my thumbs up!

THX MAN IT WAS VERY HELPFUL!!! You goa like frome me!👍

Hi there. Will this also work if the python runs from a raspberry pi? Tnx.

Hello, I need make file pdf or excel with information of Serial

Sir I got error permission Denied problem

I am getting the data from python , but there is significant gap can you help you that. Thanks in advance :)

Thank you much

hi how can i send an excel file from the pc to the arduino

great video. May I know the version of python that you are using there and the pyserial. Thanks.

If you're getting this error: arduinoData = ser.readline().decode() UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfe in position 0: invalid start byte I found out first byte that coming from arduino is can't convert with decode, so i added a loop like this ; for _ in range (0,2): arduinoData = ser.readline() i am taking first two value and don't use them and added while loop right after this loop. Full code: import serial ser = serial.Serial("COM3", baudrate = 9600, timeout=1) for _ in range (0,2): #It's giving an error for first byte so with this loop we eliminate first two byte. arduinoData = ser.readline() while 1: arduinoData = ser.readline().decode() arduinoData = int(arduinoData) arduinoData = (arduinoData/1024)*5 print(arduinoData) Ps. Yep, my bad that i don't read the error but I have searched this problem for one our and couldn't find anything :')

Thankyou

Is pit possible to print this to a webpage with cgi/python?

arduinoString = arduinoData.readline().decode("utf-8") #read the line of text from the serial port dataArray = arduinoString.split(',') #Split it into an array called dataArray may be more easy... github.com/labF212/pyhton-arduino/blob/master/test2serial3.py

I get an error that says No module named 'serial'

Please can anyone tell how to compare this arduinodata to integer value please!!!!

Can we upload python code into arduino

its not ardreno Thanks for the video.

Where do I write this code in?

do you have a link to import serial?

im confused? clearly, your audience is more educated then me. im interested in how to do what you are talking about doing using arduino with "PYSERIAL" which is a program. in order to use python you need a program to run it. two are "ATOM" and "PYCHARM" however their is something called "PYSERIAL" would you consider doing a video on how to get these programs to work, how to install them! im running Ubuntu 16.04 on 64 bit and i have "pIP" but am confused about what to download from pyserial. sorry for my "BABBLING," clearly, im confused. it appears your are doing this manually probably using an "idle" notepad that comes with python.

error: module 'serial' has no attribute 'Serial' wtf

how to convert it to int , when i use int(arduinoData) it call the error :: invalid literal for int() with base 10: ''

what version of your python?

WHY? UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

Can I read data from this device; au.element14.com/amphenol-advanced-sensors/sm-uart-04l/ir-laser-dust-sensor-97ac8394/dp/3021584 By only using my computer, and python ? Without Arduino....
