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.
Yes! Exactly, you can plug the firmata sensor readings and motor control into Node-Red to provide a dashboard UI and controls! You've got me thinking...
I was writing a touch screen controlled Python program to run on the Pi, that would probably have used I2C to communication with the Arduinos, each of which would have different devices attached. And that was my second or third attempt to build a system that worked! This seems a much simpler process that can be developed in stages, and got working very quickly: 1) Firmata on each Arduino 2) Plug devices into Arduinos 3) Set up Node-RED on Pi connected to network, with simple flows and a dashboard 4) Run dashboard on a phone or PC 5) Build the railway layout, install the servos, steppers and motor drivers, then connect everything with USB cables Then maybe one day, possibly, or maybe not: 6) Spend hours/days doing clever stuff with Python to create an all singing and dancing control system, or build a good olde fashioned control panel with lots of knobs and switches! Or both! And this could all be added to the existing Node-RED/Firmata system. Steps 1 to 4 should only take an hour or two, and I've spent many times more than that getting nowhere so far!
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 :)
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.
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)
The Arduino acts as a middleman when using Pyfirmata - so if you disconnect it from the PC it will do nothing. It needs the PC to run the code and the Arduino listens for commands, gets or sets data from its inputs & outputs and returns that to the PC.
Great video, thank you! I am new to Arduinos / programming and I have a cheap "kickstarter" robot that has an Arduino with a custom shield to control the 4 axis'. Is there any extra coding that needs to be added for the Arduino to pass through the shield to control the motors or is it as simple as calling the PIN that they are connected to?
@@kevinmcaleer28 Thank you for the fast response. I am having trouble making it my robot arm move. The shield appears to look just like the one you are using in the video, however I am connected to servo motors. Do you mind send me a quick code snippet to make the servo motor on pin 13 move. Thank you again.
Sir , if i want to use bluetooth module (HC-05) , instead of USB cable what should do (in Windows) ? . I am new to arduino and i wanted to try something new by not using C++ for arduino .
You'll need to change the serial connection settings in the sketch and add a bluetooth module to pins 2 & 3 (RX & TX). Then connect to the bluetooth device from windows and it will show up as a com port. You can then connect to that com port from Python to control it
One more thing sir Kevin. I am trying to build a RFID-enabled automated retrieval/storage and inventory system using Arduino boards. For my prototype, do you believe pyfirmata will be able to retrieve rfid data serially, put it in a pandas dataframe and finally with the help of a wxpython GUI bind pyfirmata events(or the GUI can control pyfirmata)? I hope you understand what I'm trying to ask since I really would love your insight.
hi, could you hellp me please. i've been trying for 3 days to fix the problem with pyfirmata. however it always appear ModuleNotFoundError : No module named 'pyfirmata' whenever i run on spyder IDE or command prompt. i already pip3 install pyfirmata and it's succesfully installed. please help, im dying
Good video, I do have a question. Lets say i want to build a program that shows the "Hello World" message on my pc screen when i click on a button on the arduino. Can i do this with just python and an arduino or do i still need another device?
Hi ChillaxingMuzic, Yes you can totally do this with just an Arduino and python on a PC. The PC Python script would have a loop to check the status of any messages from the Arduino, the Arduino would send a message to the PC over serial if the button was pressed
You can't use arduino libraries with firmata, the Arduino acts as a dumb terminal between its pins and the python computer its connected to. You can use python libraries to control it instead. Was there something specific you were thinking of?
@@kevinmcaleer28 Yes, i am thinking of text to speech with arduino and as python is so limitless we can do anything and exactly as you mentioned it is like ading GPIO support for arduino, thank you for your help
Tried using firmata with a motor driver. For some reason can't find it to work, even though it works in the arduino programming language (digital writing to pins works in arduino but not in python. The flashing pin code works in python though). Any advice?
no matter how many times I push the run button in visual studio it say's firmata not installed while it accepts the command just fine in pycharm. Have 0 clue what the problem is. Also I need a coder to help me build the terminator anyone interested in a serious humanoid robot project?? Hit me up please.

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

Thank you for this great video.
thanks so much kevin
I'm wondering how to use adafruit I2C sensors like the TSL2591 with Firmata. Would I need to recreate the circuitpython library in firmata?
Hey this is very useful content , good work
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 :)
The Python code cannot run on the Arduino as its only an 8bit processor. You therefore cannot permanently store or run the Python code on the Arduino
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)
Yes, definitely - basically any board that be programmed via the Arduino IDE can take the Firmata code
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.
You can use Bluetooth to connect both
Thank you for this video. Will it work for Python 3.12?
Yeah, should do! Have you tried it?
OMG u know a lot how I wished I had a raspberry pi and an Arduino mega
I can't save the program in Arduino board like Arduino IDE . The project doesn't work without pc
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?
Yes or a Mac or raspberry pi (something that can run full Python)

The esp32 can run micropython, but I’m sure the pyfirmata will work on esp32 via the arduino ide If you select the esp32 board in board manager

Had the same issue. Make sure you are importing the correct board. I was using a Mega and asking for pins that were there. DUH!!! I homered it.
