Python Tutorial - How to Display Serial (Arduino) Data on a Scrollable Tkinter GUI

-------------------------------------------------------------------------------------------------------------------------

These tutorials assume some basic understanding of Python syntax. If you are a beginner, there are plenty of resources available to quickly learn enough syntax to follow along.

Thank you so much

Thank you for making serial comm videos, they're very helpful. Would love to see more serial, uart, rs232 stuff.

Thanks for this tutorial, very well explained :)

can you plot the graph with that Temp data?

[robsonsab]

how create a button to refresh the port?

[mohamedhm]

pleasse how to copy the text in frame or i get the value of fram ?

[brunofernandes]

on the arduino you just use serial.print to write the data into the gui??

Hi. Fascinating video. Tq!

Update.... No. It was all fine, and not because I'm using /dev/ttyUSB ports.
It was because I didn't have any device plugged in! lol.
The button with the label "/dev/ttyUSB0 - USB2.0-Serial" appeared :):):)
when I ran the script after plugging in an arduino.
- Just in case other amateurs like me have the same problem.

At 5:43 I get the empty grey screen but no buttons are displayed.
I'm running linux and python 3.8.10
I;m guessing it's because ports in linux are named /dev/ttyUSBx instead of "COMx" in windows,
but my programming skills are very weak so I don't know how to make it work in Linux.
Do you (ar anyone else) have any idea?

P.S. I'm using geany text/code editor, and it wouldn't compile initially.
I had to do this to get geany to compile it...
Build > Set Build Commands.
In the "Python commands" category, clicking on the visually empty 'Command' field,
this instantly pops up... python -m py_compile "%f"
Change python -m py_compile "%f" to this... python3 "%f"

hi, may I ask why I follow urs cooding exactly the same I get AttributeError: 'list' object has no attribute 'idex'

Hi! Thanks so much for the video! Helped me understand a lot but for some reason I can’t seem to get the serial output to the window using your exact code. The code figured out the comm port and the baudrate (i.e., print on the command line shows it’s all good), and the Arduino serial monitor also works fine, but nothing is printing in the TPK window…

Any help would be much appreciated!
