two way communication between Arduino and a website

hi all,

i have arduino ethernet arduino mega 2560. managed display webpage contain textbox , button. new arduino , html, not sure whether writing code. want use javascript return me textbox's value that  being entered , update url arduino can detect.
for example if write value 2 inside text box , click button, in html display current value become 2 next textbox , url become http://192.98.40.2/?2.
i want let arduino know current value 2 well.

here code:
code: [select]
client.println("<htmlhead>");
         client.println("<body>");
         client.println("motor <p>please enter value of motor     current value =checkform() ");
         client.print("</p>");
         client.println("<form method=\"post\" action=\"http://");
         client.print(domain);
         client.print("m\" onsubmit=\"return checkform()\"><input type=\"text\"id=\"mtr\" /><input type=\"submit\" /></form>");
         client.println("<script type=\"text/javascript\"> function checkform() { var mvalue = document.getelementbyid(\"mtr\"); string mv; mv=   mvalue.value; return mv;)}</script>");
      client.println("</body><html>");


thanks in advance. appreciated!!!

you don't need javascript this. page should contain form submit button. action submit should same original request page. submitted request have ? , other stuff appended, depending on form field names , field contents.

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
