Hey everyone, thanks for stopping by! The joystick/servo problem is easily solvable and most folks have been able to get it working -- it just takes a USB joystick, an Arduino (or clone), and the Python scripting language (okay, and a bit of patience, too!). Python is installed by default on MacOS X and Linux, and is easily installed on Windows.

The most up-to-date information on controlling servos with a USB joystick can be found by reading Arduino-Python 4-Axis Servo Control. The article is quite detailed, and most of the common problems have been identified and solved in the comments section. Thanks!

Hello Brian ! Can I use a usb joystick ? In this case what’s a right program ? Thank’s

I see what is missing, some store which would supply a working joystick with arduiono servo connection. I would pay a double price.

hey there. nice guide.

Im working on the same thing as you, but wanted to try an xbox or psp controller. do anyone have a nice tutorial how to read the signal from the usb cabel, through my pc and WiFi to the Rover/arduino?

im stuck with alot of ideas but dont have the skills in this field to make em come to life =)

Great project, I really need joystick which controls servo! It is clear with arduino interface. Could you please describe in short steps what to do with pigame, piserial, python’s standard library? Sorry guys I am from physics, I never did programming, it is difficult to understand how to run both programs (python, arduino) simultaneously in windows-xp for a joystick servo control? As I understand when we start python COM must be for joystick and arduino has different COM. Please give me all steps, we install, start command, type such command… for windows I am most grateful to you.

Hello, great project.

Please, do you know some method to link an USB phone connection directly to a servo ?

hey… I would be very thankful to you if you could give the full code for the joystick control of a single servo.The reason why i am asking is that ….its a bit difficult for newbies like me to interpret the code and play with it(The one which is given above doesnt explain which one to be run in python and which one to be loaded onto the freeduino board )…I would be thankful to you if you could do that as soon as possible [:)]

Good work. I tried to replicate the work but found a weird problem on the py script using pyserial. The communication works good under python shell, but failed in python script. For example, the python code did not print "hello". I tried this code on different Windows PCs. Did you observe similiar problems? Thanks.

Python code

import serial
ss = serial.Serial(port='COM7',baudrate=9600,parity=serial.PARITYNONE,stopbits=serial.STOPBITSONE,bytesize=serial.EIGHTBITS)
ss.write('A')
ss.flush()
print ss.read(ss.inWaiting())

Arduino code

void setup()
{
  Serial.begin(9600);
}
void loop()
{
  int b = 0;
  if(Serial.available())
  {
      b = Serial.read();
      Serial.println("HELLO");
  }
}

@Jason: Sorry, no. I’m sure they’re out there, I just don’t have much experience with different types. Mine are definitely loud!
