Control Arduino with Python using Firmata / PyFirmata

Do you want to control an Arduino using Python, well you kind of can using Firmata and PyFirmata. I say kind of can because you will need another device running Python to control the Arduino as a remote device using the Firmata Protocol.

Awesome stuff. Thank you. people like you help us get more closer in building things our own and pursuing our passion.

Nice video. well structured, informative and not rushed. just got yourself a new sub!

[EcoHamletsUK]

Brilliant. I think Firmata may be what I've been looking for to control model railway layouts, with a Pi to control everything, and several Arduinos connected by USB or Bluetooth to drive servos, stepper motors and motor drivers. It would save a lot of work writing individual sketches for each Arduino. Even better, it looks like I could use Node-RED instead of writing any Python code, at least to get it all working, then write a really flashy Python program later if I want to. Node-RED could work for robots too.

[iKostanCom]

That is very interesting. I did not hear about Firmata and it looks like an easy way to communicate between any Pi device to Arduino. Thanks.

[NovaLink-v]

it brilliant just what i needed and can you please make like a small crash course on projects with python language along side firmata

[Lord-Black__]

Thanks a lot I have been looking for that explanation!!

[XPowerfullXPlayerX]

Hey this is very useful content, good work

[omarsalah]

awesome tutorial sir, couldn't be better.
i was wondering if this was applicable to other types of arduinos (other than the mega and uno)

[BUILDwithMAULIK]

very informative turorial. Can we use pyfirmata to control the robot without it being plugged into the computer (from battery power)?
since the code is working form the PC directly and not uploaded on the Arduino itself.

[عبدالرحمنالمرنخ]

If you disconnect the Arduino from the device, the code does not work with another power source
I have to plug it into the computer
What is the solution to permanently store the code on the Arduino like the Arduino IDE?
I thank you very much for this excellent explanation :)

[TheCeremoniesOfIsrael]

OMG u know a lot how I wished I had a raspberry pi and an Arduino mega

[NicholasWong-vvnn]

I'm wondering how to use adafruit I2C sensors like the TSL2591 with Firmata. Would I need to recreate the circuitpython library in firmata?

[michaeljwosniak]

Hello Mr McAleer. I'm really interested in this topic. could you tell me, does the Arduino have to stay connected to the PC for the pyfirmata code to work? or can the system operate just fine without being continually connected? (of course, after the code is uploaded)

[JesusGonzalez-rdqn]

Quick question, how do you import an arduino library in out python sketch using PyFirmata?

[AdamKaszok]

Thank you for this video. Will it work for Python 3.12?

[yefriencarnacion]

Thank you so much for the tutorial, i loved it! So... to work arduino with python the arduino need to be connected with a pc right?

[mohamedjbaili]

I can't save the program in Arduino board like Arduino IDE . The project doesn't work without pc
