How to link arduino serial to python!

download python here https://www.python.org/downloads/

Then go to the python source file location

And copy it

Next open command prompt

And type in these commands

cd <paste the source of the python file here>
py -m pip install -- upgrade pip
py -m pip install pyserial

Pyserial is for reading the arduinos serial port

Next open the python ide

And copy this code into it

#///////////////////
#/ By polyhedra64  /
#///////////////////
import serial
import time
Arduino =serial.Serial('com3',9600)
while 1:
  data  =  str(Arduino.readline().decode('ascii'))   #read the data
  print(data)
  time.sleep(0.1)

Finally

Go into device manager

And below network adapters there should be "Arduino Uno (COM3)"

if not contact me in comments

Last of all setup the arduino project itself

/*
By polyhedra64
*/
void setup() {
 // put your setup code here, to run once:
 Serial.begin(9600);
}
void loop() {
 // put your main code here, to run repeatedly:
 Serial.println(analogRead(A0));
 delay(100);
}

All thats left is to run the arduino project

Then run the python project

If any issues arise contact me in the comments and I will reply relatively fast

You should see the string of numbers from the potentiometer appear in the idle

This is useful because python is very well rounded and powerful so having Arduino being able to link up to it is incredibly useful
