Arduino with Python LESSON 11: Graphing and Plotting Live Data from Arduino with Matplotlib

[paulo.galvao]

In Python 3 i think numpy is not necessary for this. To work this program as to change line 30 to: arduinoString = #read the line of text from the serial port

10 years later and I'm still learning ! Thanks Paul, more spanners in the toolkit!

I have learnt more today than I have in 2 Years by watching these videos. You Sir are a good teacher and I like the way you make mistakes in spelling and admit that you have done it. I am now a net-pupil of yours. Thanks.

i have done this lesson with a joystick and its awesome. plotted x values and the y values in the graph

[MemoMedranoo]

Paul, I wanna say thanks, this script saved my project, I'm doing a multivariable sensorial module. It tracks voltage and current from a 3 phase motor. Collecting data from 3 arduinos at the sime time, I adapted this code and it works perfectly. Keep doing videos like this, you are a great teacher!!

your series of lessons has really helped me out regarding getting a start on my python learning curve. nothing better than someone stepping you through it one thing at a time, explaining it all as you go. I have learnt how to program html, action script, basic, arduino all without any schooling, but at times it is very difficult without the kind of support you get from an actual class. There are many gaps in my knowledge which most professional programmers would find comical.. so again I appreciate you putting these lessons out there for people like me as I find it has filled in quite a few gaps I had while trying to figure out python on my own so far. thanks! please resist the urge to make your videos ' members only content' or something like that... share the knowledge and it'll come back to you ten fold.

I'm an old dog learning new tricks and I am enjoying your videos. What a fun way to learn new things. You are an excellent instructor. If I had had teachers like you those many years ago, I might have actually been interested in school. :-) At the time I was more interested in the projects I was doing at home on my own.

i have seen every single lecture of you from arduino #1. all of them just the best of the

[karthikvigneshwar]

I just want to wholeheartedly thank you for this channel and all your lessons. They have been very helpful and the way you teach also motivates me to try and emulate the same when I try and teach others. Thanks again!

[yuanfang]

thank you so much for solving my problem in sending multiple values from arduino to python. I'm really new to serial communication and searched a lot of methods but only yours works!

[eddiekvh]

You're a true teacher. I've learned a ton here. Thanks!

[shailf]

hi, i am new to both python and arduino. and i am glad that i came to this tutorial first. Brilliantly explained. Thanks a lot.

[shanee]

You are an excellent teacher, Paul.  I found your tutorials while looking for information on Matplotlib for Python and Raspberry Pi.  I am working on a project at work to automate a particular calibration chore.  I've since viewed several of your tutorials and will be watching the rest soon.  Thank you so much for making this information so clear and easy to understand. 

[zeylien]

Thank you very much for these good arduino python tutorials :-)

My plotting was slow when using the drawnow() function, there was a few seconds delay between the plot and me activating the sensor. But when i instead inside the loop used the plt.plot() function with a plt.cla() //clears the plot after, it was able to plot at nearly live speed.  

[Zugadizayn]

Thank you so much. you are my master ! Best teacher ever !! Your teaching skills and your style is OMG ! absolutely amazing. !!!

Great work Paul. I've missed all of your lessons, but you made this simple enough for me to understand. Thank you!

[sacredinclinations]

-thanks so much for this video I have been contemplating getting into microelectronics for a while and your lesson just sealed the deal. I subscribed and I guess its now time to buy stuff!

[rsyoung]

Lucid, clear explanation, thanks for posting! I especially benefit for line by line discussion of not just wha, t by why you're doing what you're doing...

[freeelectron]

The scaling and data range updating was really useful and also your enthusiasm is infectious! :)

[parasbhanot]

This is easy with matplotlib and python but it is a nightmare with jfreechart and j2d charts in java . i am glad that i found this tutorial series .thanks
