UART between arduino UNO and pc via USB not in sync
I connected my arduino uno to my system and then using serial tried writing and reading data but there is a problem which I found when I tried giving arduino crafted messages. My arduino code is pretty simple.
void setup() { Serial.begin(115200);
}
void loop() { if (Serial.available() > 0) { String data = Serial.readStringUntil('\n'); Serial.print(" You sent me: "); Serial.println(data); } }
and my python code on my system
#!/usr/bin/env python3 import serial import time
if name == 'main': ser = serial.Serial('/dev/ttyACM0', 115200, timeout=1) ser.flush()
while True:
string=input("Enter the string: ")
ser.write(str.encode(string))
line = ser.readline().decode('utf-8').rstrip()
print(line)
time.sleep(0.01)
Now this gives me ability to write instructions to my arduino but following sequences of communication occur

Looking at them I understand that this might be a problem with my code or I am using the wrong protocol.
