Help!!!
!I got 6 hours to submit a project! -
I havent messd it up, but i was thinking
how will I be able to get a software slider instead of a potentionmeter? (E.g. instead of controlling somethign called sensorValue with a potentiometer and analogRead(), Would i be able to use a software slider instead?)
Im not going to make a application,
just a web interface with the arduino ethernet shield. (I would like to connect it to the android as well though wifi)
tl;dr: using a software slider
e.g - http://www.biemmeitalia.net/blog/?p=166 in the youtube video where he uses a slider for PWM? Please help! this is a vital part of my project 
Thanks in advance to anyone who cares to help a noob 
(Not a complete one, though 
)
Jubito?
Is there any other way? Is it even possible with jubito?
wtf is jubito?
Why the hell are you proposing jubito and then asking us what it is?
There are lots of ways to achieve what you're describing.
One option is to write your user interface as a Processing application that runs on a PC with a USB connection to the Arduino.
Another is to use Firmata as the mechanism to communicate from your user interface to the Arduino. I believe there is a thin client version of Firmata although I haven't used it.
Another option is to have the Arduino host a web server which presents a web page with your user interface in, and design the web page and web server so that a slider on the page sends movement events to the Arduino e.g. using some sort of AJAX based approach.
Another option is to host the web app providing your UI on a PC and have that web app send commands to the Arduino via a web service hosted on the Arduino.
This is far from an exhaustive list. You need to identify what UI technology you're familiar with or capable or learning in the time available, and design your solution around that.

Sorry, that was a keyword in my search so i decided to get some help
Thank you for the suggestions, i'll try Firmata, or a web server with ajax

Hey zoom, I tried your webpage, but I get nothing but a blank page. Why? What can I do?
Hey zoom, I tried your webpage, but I get nothing but a blank page. Why? What can I do?
Not sure what your problem is, but note that the files used in the code I posted are served from an SD disk on the arduino Ethernet shield, and the link provided in the code info section has the Ethernet shield using a LAN IP address and port 84, 192.168.1.102:84 Below is the same basic slider page served from my ISP's web server.

Yes, I dwnloaded the files and put them on the sd card. still not working

Perhaps you should post your code.
