I'm trying to send 3 ints in the range of 0-180 from Python to the Arduino Uno device using pySerial (py3K). I have managed to send 1 int by using python's struct lib (not sure if it's the best or fastest way but it works).

However I'm failing to send more than 1 and every example online seems to stop at 1.

Here's the simplified code. The task is to send servo0-servo4 to the Arduino and apply those values to the corresponding servos.

Python Code

import serial import struct import time bge.arduino = serial.Serial('/dev/ttyACM0', 9600) # let it initialize time.sleep(2) # send the first int in binary format bge.arduino.write(struct.pack('>B', 45)) 

Arduino code

#include <Servo.h> Servo servo0; Servo servo1; Servo servo2; void setup(){ Serial.begin(9600); servo0.attach(3); servo1.attach(5); servo2.attach(6); } void loop(){ if(Serial.available()){ int message = Serial.read(); // control the servo servo0.write(message); } }
