I want to use python to open and run an Arduino file

Projects Programming
1

Can I just tell the python to open a particular Arduino file and run it?
I have a python program, when it run to a certain steps, If true, I want it turns to run a Arduino program. I try pyserial library, I tried pyfirmata2, I tried RPI.GPIO, all have problems,
So at the end of the day, can I just ask python, to open a given arduino file name and please run it.

What exactly do you mean by "run it"? Do you mean run the code on a PC, or download the code to an Arduino and run it?

You could use python to compile and upload a particular sketch to an Arduino using the arduino-cli tool.

'import cv2 'import numpy as np 'from pyzbar.pyzbar import decode 'import pyfirmata 'from pyfirmata import Arduino, SERVO 'import time

'cap = cv2.VideoCapture('http://192.168.86.1:81/stream')

'cap.set(3,640)
'cap.set(4,480)

'with open('order.txt')as f:
' myDataList = f.read().splitlines()

'while True:

' success, img = cap.read()
' for barcode in decode(img):
' myData = barcode.data.decode('utf-8')
' print(myData)

' if myData in myDataList:
' print('Authorized')
' digitalWrite(2,50)
' else:
' print('Un-Authorized')

' pts = np.array([barcode.polygon],np.int32)
' pts = pts.reshape((-1,1,2))
' cv2.polylines(img,[pts],True,(255,0,255),5)
' pts2 = barcode.rect
' 'cv2.putText(img,myData,'(pts2[0],pts2[1]),cv2.FONT_HERSHEY_SCRIPT_SI''MPLEX,0.9,(255,0,255),2)

'Use code tags to format code for the forum cv2.imshow('Result',img)
``Use code tags to format code for the forum` cv2.waitKey(1)

At row 14, if return a authorized text, then a want to run a servo motor. But I dont know how to ask python to run servo motor. Can I ask python to run my Arduino program for the servo motor. I just tell the python what is the arduino file name or location. Please open it

Let me study what is arduino-cli, sounds like helpful, Thank You

@greenfood1234 you can have a servo program that is running on an Arduino and you can send commands from Python to Arduino that moves the servo, is that what you wanted?

8

Yes, please, How can I do that?

you need your python code to talk to the Arduino board, possibly using the Serial line.

I've written a small tutorial on interfacing with Python. See Two ways communication between Python3 and Arduino

Hi @greenfood1234.

Arduino CLI is definitely the way to accomplish what you asked for:

However, this is an "XY problem". Using Arduino CLI ("X") is an absolutely terrible way to accomplish your true goal ("Y"):

12

Let me study first, Thank You

I follow your think way, Arduino CLI ("X") manage arduino files. I need Y to X.
I am buying new linear actuator can be programmed by python. Then no more XY interaction.
Do you know which company own python? I should go there to ask how to use Y to connect X

14

Did you get the XY reference right?

Python is owned by the Python Software Foundation, as google would tell you. They have a forum here https://discuss.python.org/

I'm not sure that they will be able to help much with Python/Arduino integration, but give it a try.
