Arduino wait for serial data from Python
I'm new to Arduino, and I'm trying to make a game. I'm sending the serial data with Python to the Arduino. I want to make the Arduino wait untill it recieves the serial data from Python.
My questions are:
- Why isn't the Arduino program working with serial data from Python, but it works with data from Serial Monitor?
- How can I make the program work with data from Python? (Wait untill serial data from Python, and then save the data.)
Arduino code:
int select;
void setup()
Serial.begin(9600);
Serial.flush();
while(!Serial.available())
if(Serial.available()>0)
select=Serial.read();
void loop()
Serial.println(select);
delay(500);
Python code:
import serial
ser=serial.Serial('COM4',9600)
ser.write(b'1235')
ser.close()
Solved the problem that I don't get the serial data, but a new problem occured:
The problem is that, if I get the serial data, my Arduino program jumps back to the while(!Serial.available()) loop, and not goes to the void loop().

A new USB connection with ser=serial.Serial('COM4',9600) resets the Arduino. The data sent right after connection are lost because the Arduino boots.

Now I get the serial data with the Arduino, but there is one problem, when I get the data the arduino program jumps back this loop: while(!Serial.available()), and not to void loop().

every time you invokeserial.Serial('COM4',9600)the Arduino resets

Like Juraj says that resets the Arduino you should add code to wait for it to come back up
import serial
ser=serial.Serial('COM4',9600)
sleep(.5)
if arduino.is_open == 1:
print("open")
ser.write(b'1235')
ser.close()
