Arduino and Python Serial Communication with PySerial Part 2 - Adding User Input

In Part 2 we go over how to add more control to our code we developed in Part 1. We add functionality to get a data only when we request it.

Thank you so much for this. Using pyserial is so much easier than using pyfirmata. This is going to help me with my every project

[RockRanchCowboy]

Helped me a lot, thanks for the tutorial!
Also, for other people learning programming, don't forget that ascii code is characters, not int's. I did, and couldn't figure out why python wasn't getting a response for hours (was checking for an integer not a char)

Excellent tutorials! Simple, clear, and very useful, not only the one on Serial Communication between Arduino and Python.

These tutorials help me a lot. I have to donate to this channel.

[MaheshKumar-ktlv]

Nice way of explaining. Easy for beginners to understand.

[rluxon]

easy to follow your lessons. thank you so much for taking the time to make the videos.

[tecnologiaelectrolichan]

muchas gracias por tus videos. saludos desde peru

[charlesklein]

consider writing a book! i have read a few and now am investigating "PROCESSING" language. your videos are better then the books. consider 3 dimensional "Vpython" or "processing"

[Electheo]

Great and helpful video! I used PyCharm to program so some things were a bit different. But you explain the functionality really well!

[EunchanPark]

I am happy that you made this video. Thank you !

[MayankSingh-tkvq]

Exactly what i want to learn, Thankyou sir.

[Heron]

Thank you for your examle and expanation. Is it possible to use such method for comunicate PC and Arduino for real time values monitoring tasks?

[najninmansuri]

Heyy, Can we not defined the input pin commands in python only, like I don't want to use ide, Can I do that?

[markbowring]

I'm at the bottom of a very steep learning curve. Can you tell me which text editor you are using with the "Run" command on the ribbon, and does this automatically bring up Python 3.5.1 Shell

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

[rajeshsingh]

Is it necessary to have a audrino code else than python code.

[niet]

Everything works but only when i type 'y', only a y without the single quotations will result in an error. Any ideas on how to fix this?

[Heron]

When l input character 'g' Arduino accepts it like iscii-code (103) and cannot compare it with the symbol 'g' in if-construction. Why?

[amiramiri]

I assume Serial.println() write the data to serial bus and then Python reads from there! but my python cannot do that because the port is alreadly busy !

[maartenv.b.]

Am I the only one that has to disconnect and reconnect the arduino after sending some code, otherwise it gives an error messege... Does somebody have a solution for this problem?

[cgowthamraja]

iam getting this error pls help me to solve

Get data point?y
Traceback (most recent call last):
File "ArduinoSerialCom.py", line 16, in <module>
userInput = input('Get data point?')
