It makes a lot of sense to use high level python code on the computer to do the heavy lifting and simplify the microcontroller code to simply sending/receiving commands from the computer.</p> <p>Thx</p> Thanks for posting this code. gave me a head start on my arduino project.

My first Arduino project will be a joystick-controlled laser pointer, so this is exactly what I needed to get started. Just got to find where I put the Saitek joystick... Cheers, Geoff.</p> G’day Brian, just wanted to say many thx for this detailed and beginner-friendly info.

Are you having problems installing <code>pyserial</code>? If that's the case, just download the <code>pyserial-2.5-rc2.tar.gz</code> file (or whatever the current version is) from the <a href="http://sourceforge.net/projects/pyserial/" rel="nofollow">Sourceforge project page</a>, then extract the file using the following command:</p> <pre><code>tar -zxvf pyserial-2.5-rc2.tar.gz </code></pre> <p>This should leave you with a directory entitled <code>pyserial-2.5-rc2</code>. Simply navigate into that directory and run the following command:</p> <pre><code>python setup.py install </code></pre> <p>This will install the <code>pyserial</code> module on your Mac, and you should be able to follow along with the rest of the tutorial from there. Let me know if you need any more help!</p> @William Hackett: Sorry, I haven’t been checking in on this blog as regularly as I should. Are you having problems installing pyserial?

I am currently working on a project in which i need to control a steering servo and ESC via an arduino duemilanove and ethernet shield. I would like to control the ESC and Servo with a joystick connected to my computer. this then transmits data from a WRT54GL to a bridged WRT54GL on the rover to control the servo and ESC.</p> <p>I am having a little trouble with making this work, do you know anywhere i could find more information on sending these commands through the ethernet shield?? Any help would be greatly appreciated, this is my major work for Design and Technology.</p> <p>Thankyou, Chris</p> Hello, great tutorial.

It goes through the motions but when I type "python" into the terminal window it stays at version 2.6.1. Maybe I should stick to flower arranging in Antarctica.

I have no idea what to do with the script, where to insert the control into python, nothing. I've even tried the python web page and cannot make the simplest script work (except hello world). I'm a hardware person and would really like to try this controller; but without some help in the input of the software; I'm dead in the water.

I am trying to implement your code by using the WiFi modules but instead of servos (don't have any) I am going to use leds. I will report back as soon as I can. Thanks for sharing such a wonderful project...</p> I have visited and poured over your articles many times regarding servo control via joystick and I haven’t read all the comments but I did make a WiFi module for micro controllers. you can find out more here http://leetgeekgear.blogspot.com/ but essentially it shows up as a serial port via an FTDI cable and transmits/receives via serial uart.

Because it moves to unwanted position before I start the program on the PC and it would be great to eliminate that.</p> Question: Is there a way to make the servos move to a predefined position on boot-up of arduino instead of going to 90 degrees as it is now with the MultipleSerialServoControl.pde?
