python - .append() method with pyserial and arduino gives me ridiculous output -


i' m trying voltage arduino, , make array them.

arduino code below:

void setup() {  serial.begin(9600);  }  void loop() {  int sensorvalue = analogread(a0); float voltage = sensorvalue*(5.0/1023);  serial.println(voltage); }

on serial monitor, seems fine.

when try make array python, used code:

import serial ser = serial.serial("com5", 9600)  voltage = []   while true:     volt = ser.readline()      voltage.insert(volt)     print voltage

just gave me not array voltage measurements. tried .apppend() , .extend(), same results.
