I want to start a project on Arduino. I m actually a newbie to the arduino.
Now getting into the project , i want to give a pan and tilt movement to a webcam through internet or intranet. i googled it and found that i need to the arduino board and arduino ethernet shield to get into action. I bought all the parts , started doing the project. I got strucked with the code.
I actually want control the servos by clicking a pushbutton in the webpage. i want to use two servos for the pan & tilt movement. Please help me on code .. please do the needful .
Are you hosting the web server on the Arduino itself? In such case you need to parse the data from the client (web browser). The web page buttons shall post some variables to the server, and the server shall parse the incoming data from the client and move the servos.

Hey thankz for the code ...it really worked for my for my project with very little manipulations....it is very much helpful to me..
But i m not satisfied with the web interface that i look at .... if anyone can help me to use some push-buttons to give the control to servo to move, it could be helpful to run my project as i wish ....
Thankz once again to charalamposdoukas & zoomkat ..
i attached my code ,which was working 100% for my project...

You can find lots of html tutorials with various buttons. below is code with mousedown activated buttons.

@jackhobbiest, as a part of my project i need to control servo motor via ethernet , so can you please provide the circuit of your project that is working ....
thank you
someone that knows how to program a adrino to control a motor over the internet please contact me, i am a 25 year old entrapenuer than has a great business idea willing to split 50/50 no questions asked for a change to retire , it is a likely business op that i have that i have the idea and don't have the programming background to get it off the ground. if your interested in hearing my idea please please contact me at colt.dunagan@gmail.com lets retire together.
