Python Forum

Hello,
New to python,I'm used to Matlab and Arduino. I have 3.10.6 python,and just downloaded current version of spyder.
All I'm trying to do is read serial data printed from Arduino analog pin, using serial in spyder and plot.Simple......so I thought.

Spyder code:

import serial

ser = serial.Serial("COM3", 115200)
import matplotlib.pyplot as plt
import numpy as np
plt.ion()
fig=plt.figure()


i=0
x=list()
y=list()
i=0

ser.close()
ser.open()
while True:

    data = ser.readline()
    print(data.decode())
    x.append(i)
    y.append(data.decode())

    plt.scatter(i, float(data.decode()))
    i += 1
    plt.show()
    plt.pause(0.0001)  # Note this correction

Spyder Error:

Not having the best time with python currently,could someone point me in right direction.I've tried going through and trying: https://packaging.python.org/en/latest/t...ages/#id18

but cmd says pip isn't recognized...even though I have,using tutorial above.


nvm, found solution had to use anaconda 3,install and then change spyder reference....super clear and easy,thanks for help.
